Title:
HYDRAULIC DEVICE WITH SWASH PLATE PLUNGER
Document Type and Number:
Japanese Patent JPH04259678
Kind Code:
A
Abstract:

PURPOSE: To suppress variation of the moment around an inclining shaft generated on a swash plate by the thrust force of plunger while the change of the oil pressure in a cylinder hole corresponding to each plunger is made gradual.

CONSTITUTION: A communication port 13a is formed between an influx port 15 and.311 efflux port 14. These ports 15, 14 are arranged so that the oil pressures in the communication port and a cylinder hole leading to it meet the conditions θ1=θ2=180°/Zxk and θ3=180°, where θ1 is the rotational angle of cylinder block corresponding to the division in which boosting is made from the pressure in the low pressure side port to the pressure in the high pressure side port, θ2 is the rotational angle of cylinder block 4 corresponding to the division in which decompression is made from the pressure in the high pressure side port to the pressure in the low pressure side port, and θ3 is the rotational angle of cylinder block from commencement of boosting to starting decompression; and further Z is the number of plungers which should be odd, while k is integer 1, 2, 3....
