A teat cup comprising a liner having movable thin-wall portions which are adapted to be differently pressurized is disclosed.

A milking system including apparatus and a method for facilitating the milking of a large number of animals in a milking parlor. Milking stalls in the parlor are arranged to provide a one way-path of travel through the parlor with a controlled entry and exit to facilitate pre- and post-milking treatment of the animals. The milking stalls are separated by an operator's pit. A platform or person mover disposed in the pit carries an operator from one milking stall to another wherein the proximity o...

Provided is a breast pump for the mother's milk, which makes it possible to obtain universal milk expression data without being affected by an individual difference, for example. The breast pump is composed of a collection container, a milk expressing member, and a negative pressure source for producing pulsated negative pressure. The milk expressing member is provided at an end with a teat cup and at an opposite end with a connector plug to the negative pressure source. The milk expressing memb...

A milking machine for milking one cow at a time and including a dry air pump 18 for providing high pressure and partial vacuum, a milk recording jar 15, a teat cluster 17, pulsating means 26, containers for wash liquid 38 and teat spray 40, tubing providing flow paths among these components and valves controlling the flow paths. The components are assembled as a unit on a mobile frame. The valves may be solenoid operated and may be controlled in groups to effect milking, milk transfer under pres...

An improved milking station is disclosed including an improved sensor for indicating premature teat cup disengagement, an improved shut-off valve mechanism, and a teat cup retraction assembly. In the outflow line of milk from the teat cup assembly, a plug with a magnet therein is gravitationally biased between the limit of travel bars. Assuming normal milk exhaustion from a cow's udder, the magnet falls to a lower position for a predetermined period of time (in the order of 4-6 seconds) and actu...

A teat cup milking inflation is disclosed which is constructed from a natural or synthetic rubber material or like elastomeric plastics material and arranged for location in a rigid shell to which a pulsating vacuum/air pressure is applied for flexing of the inflation when located on an animal's teat; the main part of the inflation having a double co-axial barrel form with the upper barrel locatable on the animal's teat and the lower barrel communicating with the upper teat barrel and a lower mi...

The head end portion of a milking inflation adapted to fit over the upper end of a teat cup shell includes a peripheral cuff adapted to surround and sealingly engage the upper rim of the shell and a substantially flat, relatively thin web section extending radially inwardly from the cuff and terminating in a raised, rounded deed which defines a circular central opening or mouth for receiving a cows' teat. A plurality of circumferentially-extending ribs are formed integrally with and extend radia...

A milking cup having a sleeve-like cup and a rubber teat holder inserted therein. The rubber teat holder has a suction sleeve portion which is connected at the lower end to a milk discharge pipe connected to a vacuum source. An underpressure relief valve is provided on the milking cup. A tube is connected to and extends between the underpressure relief valve and either the suction sleeve or a member which is connected to and is positioned between the lower end of the suction sleeve and the milk ...

The present invention features an improved milking system that provides a precise, delineated transition between the pressure and vacuum phases of a pulsator mechanism. The system features a two-valve control that provides a sharp transition between the alternating air pressure and vacuum that are supplied to a teat cup. One valve of the pulsator mechanism controls the vacuum inlet; the other valve controls the atmospheric air inlet. The electronics actuating the valves alternates the air and va...

A milking stand having a plurality of adjacent positions accommodating animals to be milked has a barrier at a rear end of the animals to be milked and a horizontal elongated locking component at a front end of the animals to be milked. The locking component has a first wave tube connected thereto and is mounted for vertical movement of the locking component and the first wave tube between a lower position wherein the locking component prevents the animals to be milked from exiting the milking s...
