Abstract

1335372 Distribution valve for hydraulic motor RIVA CALZONI SpA 2 Nov 1970 [7 Nov 1969] 52068/70 Heading F1A A rotary distributor for the supply and return of liquid to the stationary conduits 19 of an hydraulic motor, comprises a rotary member 3 provided with arcuate inlet and outlet slots 16, 17 which register with openings 18 in a non- rotatable plate 4, the plate 4 being provided with sealed recesses 18a around the permanent interconnections between the openings 18 and the conduits 19 whereby the pressure in the recess acts to prevent the contacting surfaces of the member 3 and the plate 4 from separating. The motor is of the radial piston kind having an output shaft 7 rotating the member 3. The slots 16, 17 are in communication with respective passages 10, 11 in a hollow casing, a ring 12 separating the passage 10 from the passage 11. The pressure of liquid from the passage 10 acts on an annular end surface of the member 3 surrounding the ring 12 to produce a force A urging the member 3 against the plate 4. In a similar manner, pressure from the passage 11 acts within the ring 12 to produce a force B. Since the areas of the member 3 separated by the ring 12 are identical, the forces A and B are the same whichever of the passages 10 or 11 is used as the inlet. The ring 12 may be replaced by an apertured plate, Fig.7 (not shown) providing several pressure areas which are summed to produce the forces A and B. Balancing recesses 16a, 17a for the slots 16, 17 are provided.
