Abstract

Control system for fluid circulation apparatus in which a pump supplies fluid under pressure along a supply circuit from a fluid source to a receiver; said control system including a fluid return circuit between the source and a point located in the supply circuit downstream of the pump, a main motor for driving the pump, and a normally closed circulation return valve located in the return circuit, which can be opened to allow fluid under pressure from the pump to return to the source.
