Abstract
A valve assembly with a valve member coaxially received within a valve casing and interacts with the casing to provide a one-way inlet valve at one end of the valve casing and a one-way outlet valve at the other end of the casing with an annular compartment therebetween adapted to be coupled to a variable volume compartment and thereby together provide a simplified construction for valving components of a fluid pump.
