Abstract
PURPOSE: To make it possible to select flow rate proper to various kinds of fishing equipment with the minimum number of pump by using a combination of connected by draulic pumps having different delivery flow rates and a selective switching valve.
CONSTITUTION: Oil pressure pump 21 and 22 have different dilivery flow rates. For example, the delivery flow rate ratio is assumed to be 2:1. The pumps 21 and 22 constitute a double oil pressure pump set 2, which are connected to a power source such as a motor. A flow selective switching valve 5 is installed between the double oil pressure pump set 2 and a pipe 4 which leads to an actuator. When the switching valve 5 is switched to 51 side, only the delivery flow of the hydraulic pump 22 is led to the actuator, and the delivery flow of the hydraulic pump 21 is returned to an oil container 3. When switched to 52 side, only the delivery flow of the hydraulic pump 21 is led to the actuator instead, and the delivery flow of the hydraulic pump 22 is returned to the oil container 3. When switched to 53 side, the delivery flow of the hydraulic pump 21 and 22 is led to the actuator.
