The inner space of the sleeve receives a nipple of an animal to be milked and the sleeve defines with the casing an outer space which can be connected by means of an aperture in the casing to a source of varying pressure, especially alternately applied vacuum and atmospheric pressure. At least one expandible body is provided in the outer space for exerting pressure on the sleeve to massage the nipple and, also in the outer space, an arrangement is provided which, depending on the relative pressures of the inner and outer space, controls the expansion and contraction of the expandible body. Preferably, both the expandible body and the said arrangement comprise fluid-filled cushions, the inner volumes of which are connected, fluid being transferred between the cushions depending on movement of the sleeve relative to the casing.,下面是Milking cup专利的具体信息内容。

1. A milking cup comprising a tubular casing; a resilient deformable sleeve located in said casing to extend therethrough forming an inner space to receive a nipple therein; said sleeve secured to the ends of said tubular casing to form a longitudinally extending outer space between said sleeve and said casing; at least one hollow body variable in volume and extending longitudinally through said outer space; said body comprising an upper massage portion that is variable in volume to exert pressure on said sleeve as it surrounds a nipple held therein and further comprising a lower control portion, said massage portion and said control portion having their inner volumes connected together; an aperture formed in said casing and opening to said outer space for application of varying pressures to said outer space, said varying pressure controlling contraction of the volume of said control portion to effect a corresponding change and expansion of the volume of said massage portion, and further allowing expansion of said control portion with corresponding contraction of said massage portion.
2. A milking cup according to claim 1 wherein control device means is located in said outer space, and said lower portion is located between said control device means and said casing.
