ABSTRACT:
An advance mechanism for a pump comprises a fluid operable piston arranged to have pressurized fluid applied to a first end thereof to adjust the axial position of the piston. The arrangement further comprises means for applying fluid under pressure to a part of the piston remote from the first end thereof in order to apply a torque to the piston. In one embodiment, the means for applying comprises a passage extending within the piston, the passage communicating with the first end of the piston such that high pressure fluid is received by the passage.
