Title:
SEAL DEVICE FOR PLUNGER TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JPH08145187
Kind Code:
A
Abstract:
PURPOSE: To extend the seal perforce holding time remarkably by using U and V packings and without extending a seal space.
CONSTITUTION: A seal device for plunger type compressor comprises a V packing 20 which is inserted into a clearance between a cylinder 10 and a plunger 8 reciprocated slidably on the inner surfaces of the part 1 of a cylinder 10 formed in a cylinder block 9 and of which compressive force in radial direction is large and a U packing which is inserted in a clearance between plunger 8 and the cylinder 10 and of which compressive force in radial direction is small. Thus the seal life is extended remarkably by the cooperative action of both packings.
