Abstract

PURPOSE:To make a contact part less worn, and promote a simplification of the lubricating mechanism, by applying a back pressure to the vane in such constitution with a pressure in bottom of the vane groove made becoming higher than that of the inflow chamber at the time of circulating operating fluid. CONSTITUTION:Operating fluid goes into the expansion machine from an inflow pipe 13, and is introduced to a high pressure chamber 12, a pressure reducing unit 19, an inflow chamber 20 and an inflow port 21, and linked to a rotor 1 in a cylinder 2. The action of the pressure reducing unit 19, provided in a rear wall 4, reduces a pressure of the fluid, inflowing through the inflow port 21, to lower than that of the high pressure chamber 12. On the other hand, by a link hole 16, provided in the rear wall 4, and an introducing unit 18, a pressure and lubricating oil 14 in the high pressure chamber 12 act upon a vane groove 23 through a pressure groove 15. Accordingly, a vane 24 is made to slide in the vane groove 23 and pressed to a bottom 25 of the cylinder 2, simultaneously a suitable amount of the lubricating oil is supplied.
