Abstract

1,128,240. Hydraulic reciprocating motors. M.K. KOIVUSALO. April 20, 1966 [April 22, 19651, No. 17238/66. Heading F1A. A rotary distributor valve for a multi-cylinder hydraulic motor comprises a rotary valve plate 2 mounted on the motor output member 11, e.g. a shaft, as shown, or a drum, and stationary discs 1 and 3 on either side of plate 2. Disc 1 has inlet and exhaust ports 6, 6' for each cylinder, and disc 2 has ports 7a, 8'a connected by pipe 9 to one end of a cylinder and ports 8a, 7'a connected by pipe 10 to the other end of the cylinder. Valve plate 2 has arcuate ports 7, 7' in opposite segments of the valve plate, Fig. 3 and arcuate ports 8, 8' in opposite segments between the port 7, 7' segments, ports 7, 7' registering with ports 7a, 7'a and ports 8, 8' with ports 8a, 8'a, during rotation. For the three cylinder motor described, the groups of ports in discs 1 and 3 are disposed at 120 degrees, and two sets each of ports 7, 7', 8, 8' are provided in plate 2 to give 2 strokes per revolution. Ports 6, 6' may be divided to correspond with ports 7a to 8'a.
