Abstract
A suction valve assembly of a compressor includes: a piston disposed movable in a cylinder forming a compression chamber, having a suction passage for sucking a fluid and a valve seat formed at a front side thereof; a valve body contacted to the valve seat to open and close the fluid, of which a front side making a portion of the compression chamber is formed hermetical; a support rod inserted into a rear portion of the valve body and fixed at one side of the piston and supporting the valve body to be moved in a certain range; and a release preventing unit formed between the valve body and the support rod to prevent the valve body from releasing from the support rod. A guide groove inside a compression chamber is removed to prevent generation of a dead volume, thereby improving an efficiency of a compressor.
