Description

DESCRIPTION A COMPRESSOR This invention is made of different materials used in household appliances, especially coolers. It relates to a compressor comprising a valve plate formed from

In the state of the art, it is used in household appliances, especially in coolers. One of the most important noise sources in reciprocating hermetic compressors It is the valve leaf movement at the moment of suction and discharge. From sinter or sheet materials For example, intake and exhaust from steel material used on valve plates metal valve with leaves, suction leaf and exhaust leaf at the time of suction and discharge Significant noise as a result of high-speed impacts between the screed is emerging.

International Patent No. WO 0171189, one of the known applications of the technique In its application, it occurs during the opening and closing moments of the suction leaf. a system to improve irregularities and at the same time reduce the noise generated. Patent numbered US 5,733,106, which is accepted as the closest previous technical document. noise when the refrigerant is sucked from a suction inlet. a suction chamber comprising a suction chamber to indirectly prevent the formation of A compressor with a silencer is described.

The aim of this invention is to provide its function, which is used in household appliances, especially in coolers. A valve with noise reduction using different materials, without reducing It is the realization of a compressor as in Claim 1, which includes a table.

The circulation of the circulation fluid is provided by a reciprocating hermetic compressor (1).

In the preferred application, refrigerant gas is used as the circulation fluid.

One or more enclosures containing components inside the compressor (1) (7), inside the casing (7) is a valve that allows the refrigerant gas inside to be pumped. cylinder (8) to the cylinder hole of the refrigerant gas located above the cylinder (8). a piston (9) that ensures its compression, a crank that transfers the movement from the engine. (10), a connecting rod (11), a cooler that transfers the movement taken from the crank (10) to the piston (9). ensuring that the gas reaches the cylinder (8) area without warming up, and that it is removed from the refrigerant gas. preferably plastic, which minimizes the noise that may arise from cylinder (8) with an intake silencer (12) and intake silencer (12) a cylinder head (13) connecting the cylinder (8) and the cylinder head (13) by creating a rigid and leak-proof connection between a valve plate (2), which enables the valve plate to be pressed, on one side of the valve plate (2), preferably on the side connected to the cylinder head (13), to ensure that the fluids are sucked into the cylinder (8) a suction valve leaf (3), preferably on the other side of the valve plate (2), which provides On the side connected to the cylinder (8), there is a valve that ensures the discharge of the fluids in the cylinder (8) exhaust valve leaf (4), preferably in the same form as the exhaust valve leaf (4), exhaust valve Despite the high pressure formed on the leaf (4) in a short time, the exhaust valve leaf (4) is broken or the exhaust valve leaf (4) does not open or close A device that prevents possible gas leaks that may occur due to restrictor (15), exhaust valve leaf (4) perpendicular to valve plate (2) with restrictor (15) It provides fastening in the direction of the valve plate (2). in the form that prevents turning to the right or left around the axis, for example rectangular, with one or more pins (14) in elliptical form, suction valve leaf (3) one or more suction cups to provide sealing between the cylinder (8) gasket (16) and sealing between intake muffler (12) and valve plate (2) one or more exhaust gaskets (17) and valve plate (2) to provide one or more fasteners (18) such as screws contains.

The valve plate (2) is self-forming, resistant to axial loads, preferably metal a frame (6) of material and inside the frame (6), a suction valve leaf is placed on it. When (3) and exhaust valve leaf (4) strike, vibration and noise reduction of a material, preferably a rigid plastic material, which can provide includes a damper (5).

In the embodiment of the invention, the frame (6) and the damper (5) do not fit tightly to each other. It is attached as a grinding operation and the exhaust and suction The flatness in the trepans is ensured. Especially for connections with axial and radial loads such as rivets and screw holes. In the parts where it is located, there is a frame (6) due to its rigid material structure and Due to its material structure, the damper (5) is not used in these parts.

Similarly, the oscillation of the valve leaves in order to be able to dampen the sound. The damper (5) is used in the parts that it hits by making movements and the frame (6) is not used. Also, due to the high output pressures inside the system, form and structure that will prevent the frame (6) and the damper (5) from being separated from each other. has location. In the preferred embodiment of the invention, the damper (5) (8) is larger than the cylinder (8) diameter so as to close it and the frame (6) (8) and in a form and position that will not prevent it from being attached to the cylinder head (13).

In another embodiment of the invention, the frame (6) is made of sinter or sheet metal. After it is done, the damper (5) is injected on the valve plate by injection method. is being printed. In addition, preferably by grinding operation, exhaust and suction The flatness in the trepans is ensured.

In another embodiment of the invention, the piston (9) advance, also known as the piston (9) cylinder (8) to reduce dead volume by optimizing the part protruding from the forehead surface Instead of the intake gasket (16) used for dampers (5), previously classified according to their thickness, are used.

Classified suction with this operation that can be done during the compressor (l) assembly There is no need to use gasket (16). A fixed-thickness suction gasket (16) is sufficient to use and this reduces the cost of the suction gasket (16). In addition, the classified suction gasket (16) is affected by thickness variations and Cooling due to the possibility of installing an incorrectly thick suction gasket (16) capacity variability is also minimized.

In this application, the damper (5), which is thinner than the compressor (l) valve plate (2) a suction leaf receptacle (50), a suitably shaped one Insert the suction valve leaf (51) and the suction valve leaf (51) into the suction leaf seat (50) the valve plate (2), which fixes it vertically to the valve plate (2) and to turn right or left around the axis that it fixes on its surface. one or more pins (52) in blocking form, preferably in elliptical form contains. The suction gasket (16) is able to detect level differences caused by the pin (52). It includes a pin slot (53) suitable for the pin (52) form to prevent it.

In this embodiment, the intake valve leaf (51) is larger than the cylinder (8). It is located inside the damper (5) and is fixed by means of the pin (14).

Thus, fixing can be done in all directions with a single pin (14). Piston (9) Damper with a thickness less than the valve plate (2) relative to the feed rate (5) is used. Thus, between the piston (9) and the intake valve leaf (3) distance is maintained.

In the compressor (1), which is the subject of the invention, preferably metal material leaves (3,4), valve plate (2), preferably made of metal material such as sinter or sheet metal. It is ensured that the vibration and noise caused by the impact are minimized.
