Abstract

PURPOSE: To reduce installation cost and operating cost significantly by controlling the number of pumps on a pump unit with the assistance of a single control valve.
CONSTITUTION: Main liquid supply pipe 5 is connected to supply pressure port 16 on control valve 13 and discharge pipe 2 for each one of plural pumps 1 is connected to inflow port 17 which is selectively closed by means of piston 15 in accordance with a pressure inside main liquid supply pipe 5. Under this arrangement, it is possible to control the number of pumps on a pump unit with the help of a single control valve 13. Thus the electric control part is unnecessary and installation cost, operating cost are significantly reduced.
