<p>The distributor valve is intended for a precessing hydraulic gear motor having an eccentric gear wheel (10) meshing with an internal-gear ring (3). It comprises a motor shaft (7)-drive rotary valve (8) having two annular grooves (26, 27) connecting with inlet (19) and outlet (20) respectively (via 19, 18, 15 and 16, 20). These grooves alternately connect with inlet and outlet slots at right angles to them which register with ports (17) to a housing duct (21) leading to a displacement chamber (22). Each inlet slot connects with a rotationally offset point of the groove (26) via an inclined or curved portion. Each outlet slot may be similarly connected to the groove (27).</p> |
