Abstract
A valve (2) has a body (4) defining a flow inlet (6), a flow outlet (8) and a valve chamber (10). A compression coil spring (24) is contained within the chamber (10) and its coils (32) divide the inlet (6) from the outlet (8). One end of the spring (24) is seated against a reaction block (20) and an actuating rod (16) extending into the valve chamber (10) bears on the block enabling it to be lowered or raised. This action causes the size of the helical gaps (34) between the coils (32) of the spring to be altered which adjusts the flow of fluid through the valve.
