Abstract:
A refrigerant compressor having a housing assembly incorporating therein a compressing means for compressing a refrigerant gas in a compression chamber and for discharging the compressed refrigerant gas from the compression chamber into a discharge chamber comprising:at least one discharge valve element having a base portion and a plurality of valve portions each extending from said base portion to be elastically moved to an opening position thereof providing a fluid communication between a discharge port opening to said compression chamber and said discharge chamber so that the refrigerant gas after compression is discharged from said compression chamber into said discharge chamber via said discharge port;at least one retainer element having a base end portion in contact with said base portion of said discharge valve element and having a plurality of controlling portions to control a motion of opening of said valve portions of said discharge valve element, each of said plurality of controlling portions extending from said base end portion and having a portion curved relative to the extending direction of one of said valve portions while permitting said one of said valve portions to be opened by a predetermined amount, said retainer element having front and rear surfaces coated with elastic layers, respectively; anda fixing means including a holding portion for fixedly holding said base portion of said discharge valve element, and said base end portion of said retainer element, a relieved portion arranged adjacent to said holding portion to be in registration with each of said valve portions of said discharge valve element and to prevent deformation of each of said controlling portions of said retainer element when said holding portion applies a holding force to said base end portion of said retainer element, and a support portion forming an edge portion arranged adjacent to an end portion of said relieved portion, wherein said support portion contacts said sloping portion wherein said support portion contacts said sloping portion to prevent the deformation of each of said controlling portions when said each of said controlling portions of said retainer element controls the opening of said each of said valve portions.
