Abstract

A MILK PUMP EQUIPPED WITH A SUCTION MILKING INSTALLATION ESSENTIALLY COMPRISING A BODY 1 HAVING SLEEVES 2, 3 FOR CONNECTION TO THE PRESSURE CONDUIT AND TO A COLLECTOR CONTAINER 4. IN ADDITION, IN THE CORNET IS INCORPORATED A COLLECTOR CHAMBER 5, AT THE OUTPUT 5 OF WHICH A VALVE 6 CAN BE HELD IN THE CLOSED POSITION BY THE LOW PRESSURE CREATED IN OPERATION. THIS FORM OF EMBODIMENT ALLOWS TO OBTAIN A BALANCED FUNCTIONING AND ON THE WHOLE DRAWING INSTALLATION.

Description

Cornet breast fitted to a vacuum milking installation La

  present invention relates to a cornet

  breast pump fitted to a vacuum milking system

  tion and comprising a body, a connection sleeve to a vacuum duct and a connection sleeve to a collecting container. Such cones are known and they form a

  essential component of vacuum milking systems

  tion. Such installations naturally include a suction pump, which usually creates a vacuum

  intermittent. In addition to the requirements to which the installation

  tion must satisfy for purely hygienic reasons, the proposed solutions still raise technical difficulties which, at least in part, have not been overcome

only in an unsatisfactory manner.

  Thus, the milk reaches the vacuum line, or even to the pump. To overcome this

  disadvantage, we save what is called a "volume of se-

  curity "between the horn and the pump, which

  dent a great technical complication. In addition,.

  new problems arise, for example concerning the system or the functioning proper, because the

  depression can take variable values.

  The present invention therefore relates to a breast pump remedy, to a large extent,

to existing shortfalls.

  According to the essential characteristics of the cor-

  net of the invention, the body of this horn is extended by an adjoining collecting chamber, at the outlet of which

  there is a valve which closes the communication between the

  said chamber and the collecting container when a depression is created, but releases this communication when

  said depression is not generated.

  Thanks to the collecting chamber fitted with the valve, pumping can even be carried out, for example,

  See a collecting container shaped like a pocket.

  made of plastic, since the vacuum does not act

  more on said collecting container. In addition, a

  filling can be prevented by the fact that the valve opens in good time and the pumped milk flows into the tank

collecting container.

  The new type of embodiment according to the invention solves the sealing problems and allows the use of smaller pumps, since, compared to

  known solutions, the volume under vacuum necessary for assu-

  Intermittent operation may be considered

  much smaller (thanks to the valve, no vacuum

  should only be created in the internal space of the col-

  reader, nor in the security volume, since the latter

deny is deleted).

  Another particularly important advantage; -

  resides in Milk that a constant vacuum can be applied because the system no longer contains

  variable volumes (previously, the volume of the col-

  reader varied as the filling continued).

  Finally, it should be noted that the cor-

  net of new type is extraordinarily simple to achieve

ser.

  Preferably, the collecting chamber and the sou-

  pope incorporated therein are removable, that is to say that they are fixed to the rest of the body of the horn by a nestable closure, snap-fastening or rotating or screwing (by

threaded example).

  Advantageously, the valve is formed by a hole in the bottom of the chamber and, by a shutter placed under this hole, said shutter having for example the shape of a ball made of a light metal and being placed in a sort of cage. The invention will now be described in more detail.

  detail opposite the drawing attached by way of example null-

  limitative and on which the single figure is a section

  longitudinal of the breast pump according to the invention.

  The illustrated breast pump comprises a body 1 proper, a sleeve 2 communicating with the internal space of said body and connected to a vacuum suction duct (not shown), as well as a sleeve 3 for connection to a container. manifold 4 (illustrated in dotted lines). This set is in material

  plastic and constitutes a single element.

  Inside the sleeve 3 is further arranged a collecting chamber 5 equipped with a valve 6 at its lower end 5 '. Said valve is formed by a hole 8 formed in the bottom of the chamber, and by a shutter 9 which, consisting for example of a ball made of a light material, is arranged in

a cage 10.

  The collecting chamber 5 is removably attached to the rest of the body 1 by means of a snap closure 7. The whole can thus be easily cleaned. When the body 1 of the horn is applied to the animal and a depression is created, the shutter 9 of the valve is raised to its position 9 '(illustrated by a dotted line) and it thus closes the hole 8. therefore the collecting chamber 5. As soon as the vacuum is removed, this shutter 9 falls back to its lower position and the milk accumulated in the chamber can

  flow from top to bottom in the collecting container 4.

  Naturally, instead of consisting of a ball, the shutter 9 of the valve could be replaced by a shutter of another shape, for example a member shaped like a hollow hemispherical shell guided by a tail engaged in the hole 8. We can also consider other types of shaped shutters

  valves that can be actuated by vacuum.

  It goes without saying that many modifications can be made to the breast pump described and

  shown, without departing from the scope of the invention.
