Abstract
In a compressor in which a gas passage is made to have a first and a second end portion opposite to each other and conducts a gaseous fluid from the first end portion to the second end portion, a valve seat member is press-fitted into the first end portion of the gas passage to define a valve chamber in the gas passage. A valve body is movably placed in the valve chamber for checking a back flow of the gaseous fluid only when the valve body is seated on the valve seat member. At the second end of the gas passage, a valve stopper is formed for preventing a displacement of the valve body without closing the gas passage.
Claims8
A compressor comprising:
- a gas passage having a first and a second end portion opposite to each other and being for conducting a gaseous fluid from said first end portion to said second end portion;
- a valve seat member press-fitted into said first end portion to define a valve chamber in said gas fluid;
- a valve body movably placed in said valve chamber for checking a back flow of said gaseous fluid only when said valve body is seated on said valve seat member;
- and
- a valve stopper formed at said second end for preventing a displacement of said valve body without closing said gas passage, wherein said valve body has a surface with a predetermined curvature, and said valve stopper has a surface with a stopper curvature different from said predetermined curvature.
