摘要：
A prosthetic system includes first and second parts rotatable relative to one another about a joint. The first and second parts are adapted to form at least part of a weight bearing connection between a prosthetic foot and a socket. A pump system includes a pump mechanism operatively connected to the first and second parts. Rotation of the first part and/or the second part about the joint moves the pump mechanism between an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.
