Title:
DISPLACEMENT TYPE FLUID MACHINE
Document Type and Number:
Japanese Patent JP3924817
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce inside leakage of an operating fluid and provide a rotary fluid machine of high perfoprmance by sealing an axial direction clearance of a displacer sliding part effectively, and improve efficiency by arraigning an oil holding mechanism or a seal mechanism on a displacer for partitioning a casing into a plurality of high pressure operating chamber and a low pressure operating chamber.
SOLUTION: Turning operation of a displacer 5 is carried out in a casing in which an operating fluid is sucked, and thereby, the operating fluid is sucked and delivered. An oil holding mechanism or a seal member is arranged on both end surface parts of the displacer 5, and thereby, the axial direction clearance of the end surface of the displacer 5 is effectively sealed, leakage loss is reduced, and performance and reliability are improved.
