Abstract

A pump or compressor, suitable for e.g. a paint spray, has a cylindrical body (1) with an inlet (9) for air or liquid one side, and a discharge outlet (10e at the opposite side, and the quantity discharged can be varied by rotating a spindle (3) projecting from one end (2), and which is eccentrically mounted. This spindle has a slot through it with a blade through it which slides against a similar blade. Each blade has a spigot (6) extending from it which fits into a shoe (7) which slides in a curved slot (8) inside the other end plate. Thus the effective size of the double blade is varied depending on the eccentricity of the control spindle (3) to vary the output.
