Title:
SWASH PLATE VOLUME VARIABLE CHAMBER TYPE FLUID MACHINERY
Document Type and Number:
Japanese Patent JP3940661
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide swash plate volume variable chamber type fluid machinery for enlarging an applicable pressure range against high pressure reaction force of volume variable chambers without increasing a dimension of structure, weight, and motive power loss.
SOLUTION: The swash plate volume variable chamber type fluid machinery 1 comprises: a cone body 3; a disc body 5; and a peripheral wall 9. The fluid machinery is constituted of a plurality of volume variable chambers partitioned by a plurality of partition means. The plurality of partition means are constituted by selectively combining: a plurality of partition plates 7 disposed in a groove 17 of the cone body 3 to be slidable with respect to a plurality of radius lines on a circular flat surface 5a; with a partition part A of a contact line formed between the cone body 3 and the disc body 5 mutually in linear-contact. A connecting passage 39a for guiding pressure on a high pressure side of the volume variable chambers is formed, and a pressure receiving part 45 communicating to the connecting passage 39a to receive the high pressure side pressure in a direction of the volume variable chambers is formed on at least one of back face sides of the cone body 3 and the disc body 5.
