Abstract:
1. A pump having a control mechanism for regulating an output pressure of the pump, comprising: an inlet port; an outlet port; a pumping member to pump fluid from the inlet port to the outlet port; an output adjusting mechanism to vary the output of the pump; and a pressure generator spaced apart from the pumping member and including a disc rotatable about an axis of rotation, the disc having an inlet and an outlet, both communicating with an enclosed interior volume of the disc, the inlet being radially closer to the axis of rotation than the outlet, the inlet communicating with a reservoir of working fluid and the outlet communicating with the output adjusting mechanism for operatively regulating the output pressure of the pump, wherein a pressure of the fluid supplied to the output adjusting mechanism is proportional to the rotational speed of the pressure generator.
