ABSTRACT:
A fluid pressure operated actuator, for example for controlling operation of a pneumatically driven metering pump for liquids. In a specific embodiment, the actuator is a rotary actuator and includes a piston/cylinder unit coupled at one end to a rack and pinion drive for reciprocating a rotary control valve of the pump, and at its opposite end to a valve which controls the air supply to the main liquid delivery plunger of the pump. The coupling to the air supply valve is designed to allow limited lost motion at each end of the stroke of the piston so as to ensure that the rotary valve is turned before the plunger of the pump begins to move.
