Document Type and Number:
Japanese Patent JP2974163
Kind Code:
B2
Abstract:
PURPOSE:To make graduate oil pressure change in a cylinder hole mating with each plunger, and suppress change in the moment around a swash plate inclining shaft and also the thrust synthesized load. CONSTITUTION:A distribution valve plate 7 is provided with an influx port 15 and an efflux port 14, and a communication port 13a is formed between the influx and efflux port 15, 14. These ports 15, 14 are arranged so that the oil pressures in this communication port and cylinder hole leading to it meet the conditions theta1=theta2 and theta3=180 deg., where theta1 is the rotational angle of cylinder block corresponding to the division in which boosting is made from the pressure in the port on low pressure side to the pressure in the port on high pressure side, theta2 is the rotational angle of cylinder block corresponding to the division in which decompression is made from the pressure in the port on high pressure side to the pressure in the port on low pressure side, and theta3 is the rotational angle from commencement of boosting to starting decompression.
