Title: Flow rate varying device
Inventor: SHIBANO HIROSHI
IPC: G05D7/00
Filed: 1989-07-12
Abstract: PURPOSE:To obtain the maximum flow rate in simple constitution by using a pump which is set in parallel to a flow path and feeds a fluid with pressure at a fixed discharging dlow rate and a flow rate control valve whose opening amount can be continuously varied. CONSTITUTION:The fluid discharging direction of a motor-driven fixed speed rotary pump 3 is fixed in the direction of an arrow A, and a flow rate control valve 6 is set to a branch path 5. When a valve 6 is opened, the discharging flow rate of the pump 3 is partly supplied to a flow path 1 set at the downstream of a main flow path 7. While the remaining flow rate of the pump 3 circulates a closed flow path consisting of both paths 5 and 7. In this case, the flow rate of the water 2 flowing the path 1 can be continuously changed by controlling the flow rate via the valve 6. Thus a flow rate controller like a motor speed controller, etc., can be omitted and simple constitution is attained. Furthermore the maximum flow rate is larger than the maximum natural downstream flow rate owing to application of a pump which feeds a fluid with pressure.
