Abstract

The pump (2) is controlled by a variable speed motor (1) according to a central control unit (17) which also controls a pressure limiting valve (5), overflow throttle valve (7) and a shut off valve (6). Spray gun outlets (15,16) have shut off valves (8-10) and pressure control valves (11-13) also controlled by the unit when any are switched on or off and the pressure is held at the supply line (4).
