Description

  The present invention relates to a reciprocating compressor provided with a configuration of suction valves, and more particularly, is capable of operating with at least two suction lines at different operating pressures and includes at least two “orifice valve” sets. The present invention relates to a reciprocating compressor formed with a valve configuration.

  In general, the subject matter of the present invention relates to the physical location of an “orifice valve” set in a reciprocating compressor, each of the “orifice valve” sets being configured to simplify the assembly and maintenance of the suction valve configuration as a whole. It is arranged in a specific area of the compression mechanism of the reciprocating compressor.

  As is known to those skilled in the art, a compressor includes a device that is capable of compressing a working fluid by contraction of the volume of one or more compression chambers. The working fluid is temporarily stored in the compression chamber.

  The reciprocating compressor includes, for example, a compression mechanism that causes a piston to slide in a cylinder and increase or decrease the volume of the cylinder. As is known to those skilled in the art, contraction of the volume of the compression chamber cooperates with valve switching. Valve switching is also part of the compression mechanism of the compressor.

  Therefore, it is common that the compression mechanism of the reciprocating compressor preferably used in the cooling system includes at least a discharge valve and at least a suction valve. Each valve allows a certain amount of working fluid to enter the compression chamber and then this amount of working fluid can be released from the compression chamber under high pressure.

  Usually, the inflow, ie suction, of the cooling fluid is performed when the suction valve is “open” and the discharge valve is “closed”. In contrast, cooling fluid discharge, or drainage, occurs when the suction valve is “closed” and the drain valve is “open”.

  According to the current state of the art, bypass type valves are typically used for reciprocating compressors applied to cooling systems. This bypass type valve is formed by a metal blade that can change its operating state (open to closed and from closed to open) based on the pressure differential in the compression chamber. With this type of operation in mind, current bypass type valves (for either suction or discharge) can be defined as automatic valves. That is, the change in the operating state of the valve is performed without the interference of an external operator.

  The use of this type of valve is extremely beneficial. That is, there is no need for an electronic system or drive responsible for switching the operating state of the valve.

  In the most conventional situation in the art, the compression mechanism of a reciprocating compressor used in a cooling system is basically formed by a compression cylinder, a valve plate and a movable piston, and the top of the movable piston, It can be noted that the space defined between the inner surface of the wall and the valve plate forms a compression chamber whose volume changes in response to the movement of the movable piston. In these basic known embodiments, only one suction set is provided on the suction valve and operates in cooperation with the respective suction orifices of the suction valve, and only one discharge set is provided on the discharge valve. , In cooperation with the respective discharge orifices of the discharge valve. Conventionally, both a suction set and a discharge set are arranged on the valve plate of a reciprocating compressor. As is known to those skilled in the art, the suction valve is adjusted towards the inside of the compression chamber and the exhaust valve is adjusted towards the outside of the compression chamber.

  Therefore, when the suction valve receives suction pressure, the suction valve tends to move toward the movable piston. In contrast, when the discharge valve is subjected to discharge pressure, the discharge valve tends to move outside the discharge chamber. Thus, it is known that the assembly, sizing and operation of the suction valve is more complex than the assembly, sizing and operation of the discharge valve. In the current state of the art, for example, a concave shape is provided on the top of the movable piston to avoid contact between the movable piston and the suction valve.

  In addition to the basic embodiments described above, the state of the art provides embodiments of reciprocating compressors that can be driven by a plurality of different suction lines in a reciprocating compressor, i.e., a plurality of suction pressures of different values. . These compressors are known as multi-suction reciprocating compressors.

  An example of a multi-suction reciprocating compressor is described in the document Brazil published patent application 1001359.

  Broadly speaking, and as described in the above-referenced document FR 1001359, it is possible for a single compression mechanism to operate solely with one of at least two suction lines. .

  Thus, the reciprocating compressor is provided with a suction valve arrangement comprising at least two suction sets, each of the two suction sets being provided with a suction valve operating in cooperation with its respective suction orifice. It has been. Obviously, a further discharge set is provided.

  As described in document FR 1001359, both the exhaust set and the suction set are arranged on a single valve plate belonging to the compression mechanism of the reciprocating compressor. Thus, both suction orifices and suction valve anchoring means are anchored or arranged on the valve plate.

  It should further be noted that one of the suction sets also comprises an electromagnetic field generating element. This electromagnetic field generating element can assist and / or prevent switching of the operating state of the suction valve (from open to closed and from closed to open). It is thus confirmed that the suction valve can be driven electronically (by an electromagnetic field generating element) and / or automatically (by a pressure difference in the compression chamber). With this type of operation in mind, it is possible to define that the suction valve is a semi-automatic or semi-command type valve.

  Therefore, the reciprocating compressor of the referenced document Brazil published patent application 1001359 has a suction valve configuration with a semi-command suction set and an automatic suction set; It is possible to confirm that the semi-command type suction set and the automatic type suction set are not activated at the same time.

  Therefore, if it is desirable to select (act with) the suction pressure, it is sufficient to not activate the electromagnetic field generating element. Under this circumstance, the suction pressure just keeps the suction valve open and also keeps the suction valve closed. If it is desired to select (act with) the suction pressure, it is sufficient to activate the electromagnetic field generating element. Under such circumstances, the magnetic field generated by this element will block the suction orifice, block the suction pressure, and allow the suction pressure to keep the suction valve open to the suction orifice. In addition, the suction valve is attracted.

  The concept of a multi-suction compressor described in the document Brazilian patent application 1001359 is very interesting and allows an improvement of a cooling system with a plurality of evaporators, so that each evaporator has its own suction. It can have a line and can be driven independently of other evaporators. This choice of drive is made to the compressor itself by a single drive of the electrical coil. However, even though the basic concept described above is beneficial and revolutionary, the embodiments provided in the referenced document Brazilian Patent Application No. 1001359 can be simplified and improved. There are various aspects.

  One such aspect relates to the current position of the suction set that is placed in close proximity on the valve plate of the compressor. Because of their close proximity, the assembly of this configuration of suction valves is very problematic, especially when the compressor is a miniaturized compressor, so there is little physical space for the assembly.

  As is known to those skilled in the art, one of the main causes of inefficiencies in reciprocating compressors is due to energy loss caused by the outflow of cooling fluid through the suction valve. Therefore, in the development of the compressor, efforts are made to maximize the passage area of the effluent fluid between the suction valve and its respective orifice. This is usually limited by the reliability requirements of bypass and / or dimensional limitations, because the space on the valve plate is limited.

  Furthermore, it should be further noted that the introduction of an electromagnetic field generator into the valve plate is still very problematic with regard to the proximity between the suction sets, which considerably limits the space for the assembly.

  Based on this background, the present invention was made from the viewpoint of improving this spatial aspect.

  However, the subject matter of the present invention provides a configuration in which an "orifice valve" set is disposed on different components of a reciprocating compressor, thereby enabling simplification of the size of the components forming the compressor. It is included.

  A first embodiment is shown in FIG.

  As shown in FIG. 1, an “orifice valve” set 41 (suction orifice 51, suction valve 61 cooperating with each suction orifice 51, and electromagnetic field generation capable of selectively interacting with suction valve 61. Element 71) is suitably provided on the compression cylinder 1 of the reciprocating compressor.

  More specifically, the suction valve 61 is fixed to a kind of sub chamber in fluid communication with the inside of the compression cylinder 1 by the suction orifice 51 (in accordance with the present invention, the valve fixing means of each orifice is Can occur in various forms related to the state of the art).

  Optionally and further according to this first embodiment, an “orifice valve” set 42 may be disposed on the movable piston 3 of the reciprocating compressor.

  Further in this regard, it is worthwhile to disclose that the above-mentioned sub-chamber can provide a two function environment. That is, an environment suitable for assembling the “orifice valve” set 41 and an environment having an acoustic optimization function (suction muffler) at the same time.

  A second embodiment is shown in FIG.

  As shown in FIG. 2, an “orifice valve” set 41 (suction orifices 51, suction valves 61 that operate in cooperation with the respective suction orifices 51, and suction valves 61 can selectively interact with each other. A suitable electromagnetic field generating element 71) is arranged on the valve plate 2 of the reciprocating compressor.

The suction orifice 51 itself includes a hollow orifice formed on the valve plate 2. In accordance with the present invention, the valve anchoring means on each orifice can occur in a variety of forms related to the state of the art.

  With further reference to FIG. 2, an "orifice valve" set 42 (suitably equipped with suction orifices 52 and suction valves 62 operating in conjunction with each suction orifice 52) is used to compress the reciprocating compressor. It should be noted that this type of arrangement is already known by those skilled in the art.

  The great advantage of these embodiments over the state of the art (especially the state of the art described in the document Brazil published patent application 1001359) is a semi-command valve (suction valve 61 and its electromagnetic field generating element 71). Relates to the fact that the different components of the reciprocating compressor are arranged “away” from the automatic valve (suction valve 62). This makes it possible to use the space for the assembly of the “orifice valve” set 41 as a whole, more specifically, the space for the assembly of the electromagnetic field generating element 71 attached to the “orifice valve” set 41 as a whole. Is possible, thereby enabling a compact compressor embodiment that is feasible and feasible.

  While examples of preferred embodiments of the invention have been described, it should be understood that the scope of this patent may include other potential variations that are limited only by the content of the claims.
