Abstract
1395404 Rotary positive-displacement motors HYDRO-MECA 18 July 1972 [2 Aug 1971] 33605/72 Heading F1F An hydraulic externally-meshing gear motor comprises passages 7 leading from the main inlet passage 4 to zones 8 substantially opposite to the zones of the gear-wheels 1 on which inlet fluidpressure acts. Thus the forces F a1 , F a2 acting on the wheels 1 due to pressure at inlet 4, are counter balanced by forces F b1 , F b2 acting on the wheels 1 in the region of zones 8. The resultant forces R 1 , R 2 are small enough so that, even if they act on plain bearings on which the wheels are rotatably mounted, starting of the motor is facilitated. Means 10 are described for closing passages 7 after the motor has been started, Fig. 2 (not shown). Zones 8 may extend over a wider area than that shown in Fig. 1, Fig. 3 (not shown).
