Abstract: Disclosed is a positive displacement expander equipped with an expansion mechanism in which power is generated using fluid energy produced while a high-pressure fluid, supplied to a plurality of expansion chambers partitioned by an orbiting scroll or a rolling piston, is being expanded and decompressed. The expander includes a communicating pipe that allows each of the expansion chambers to communicate with an expander discharge side and an opening and closing device disposed on the communicating pipe. When supply of the high-pressure fluid is stopped, the opening and closing device is opened by the time when high and low pressures between each of the expansion chambers and the expander discharge side are equalized, thus stopping the orbiting scroll or the rolling piston at a predetermined position so that an expander obtains sufficient driving force when resuming.

Abstract: An independent control means to govern the operation of a fluid pressure device having a stator element and a rotor element constituting a stator-rotor mechanism, in which the stator element has a fixed axis and in which the rotor element has a movable axis with said rotor element having a rotational movement about its own axis and an orbital movement about the fixed axis. The entrance of fluid to the stator-rotor mechanism and the exit of fluid from the stator-rotor mechanism is governed by a rotary valve in the fluid pressure device. The independent control means features an actuating means for rotating the rotary valve independently of the rotor element by which the rotary valve is usually driven. The independent control means also features a by-pass valve which, when operated, fluidly interconnects the inlet and outlet ports of the fluid pressure device, whereby the rotor element may be stopped instantly.
