Device for stimulating an udder during milking

摘要

The invention relates to a device for stimulating an udder during milking, made up of a housing with a first connection (350, 351) and a second connection (352, 353), which housing can be grasped by a hand. The first connection connects the housing to a pulsator and the second connection connects the housing to a teat cup. A throttle valve (305, 306) is interposed between the first connection and the second connection. A control device (309) is housed in the housing and is adapted to bring the throttle valve, after a defined duration, from a partially open to an open position.

主权项

1. A device for stimulating an udder during milking comprising:
a housing that can be grasped by a hand and that has a first connection and a second connection, the first connection connecting the housing to a first line that is at least partially outside the housing, the first line connecting the housing to a pulsator outside the housing, and the second connection connecting the housing to a second line that is at least partially outside the housing, the second line connecting the housing to a teat cup; a first throttle valve interposed in the housing between the first connection and the second connection; and a control device housed in the housing and designed to move the first throttle valve from a partially closed position into an open position after a specified length of time that includes at least one complete pulse cycle of the pulsator, wherein the control device comprises:
a volume sealed off by a membrane that is in a fluid flow connection with the first connection, an exterior side of the membrane being exposed to atmospheric pressure;a transmission device for converting movements of the membrane that are caused by pressure differences in the volume into a rotational movement of a toothed wheel;a slide valve that acts on the first throttle valve and is designed to be slid as a result of the rotational movement of the toothed wheel; andthe slide valve has a projection on a side facing away from the throttle valve, the projection engages in a groove formed in the toothed wheel, the slide valve is configured to move back and forth by the rotational movement of the toothed wheel.
