ABSTRACT:
A plunger pump wherein the plunger is reciprocable in a barrel by a tappet which is coupled to the plunger by a pressure member. The tappet is reciprocable by a rotary cam in conjunction with a coil spring and is movable axially of the plunger by a first drive having a sleeve surrounding the barrel and having jaws in engagement with complementary jaws of the pressure member. Rotation of the pressure member in response to rotation of the sleeve entails axial movement of the tappet because the latter has threads in mesh with complementary threads of the pressure member whereby the tappet changes the length of forward and return strokes of the plunger. The latter has a control edge which can regulate the volume of outflowing liquid in response to rotation of the plunger on actuation of a second drive having a second rotary sleeve with jaws engaging complementary jaws of the plunger.
