Abstract

PURPOSE: To reduce the loss of flow pressure and to obtain a small-sized compact construction in a hydrostatic gear device in which an outward-toothed gear is rotated inside an inward-toothed gear and rotary slide valves are provided on both sides of the inward-toothed gear.
CONSTITUTION: To the inner teeth of a casing 1 of an inward-toothed gear, a star- shaped part 2 of an outward-toothed gear with smaller number of teeth is engaged for forming expansion and contraction chambers A1WA7 between both teeth. On both sides of the above-written inward-toothed gear 1, passage casings 3 and 4 with axial passages 31W37, and 41W47 respectively connected with chambers A1W A7 are arranged, while on other sides of casings 3 and 4, valve casings 5 and 6 are respectively arranged. In bores of these casings 5 and 6, thick cylindrical valves 7 and 8 are respectively provided to be freely rotated, and on their outsides, axial passages 71W76, and 81W86 are formed to be successively connected and disconnected with axial passages 51W57, and 61W67 in valve casings 5 and 6.
