Abstract

PURPOSE: To provide a Jerotor type hydraulic motor which can change its operational speed in two steps by itselt, by connecting a portion of the exhaust passage of a fluid pressure converting section to a fluid inlet port via a selector valve and an indenpendent valve port of a distributor valve.
CONSTITUTION: A portion of the exhaust passage of a fluid pressure converting section 1 is connected to a fluid inlet port 21 via a selector valve 26 and an independent valve port 18 of a distrubutor valve 13. By thus making a portion of a hydraulic chamber in the fluid pressure converting section inoperative, the capacity of the section 1 can be rendered virtually variable. Therefore, it is enabled to shift the operational mode of a Jerotor type motor in use of the distributor valve 13 having a single valve element between a low-speed, high-output mode and a high- speed, low-output mode.
