Claims
- 1. A method of manufacturing a reciprocating compressor comprising a cylinder block forming a compression chamber; a cylinder head connected to the cylinder block and forming a discharge chamber; a discharge valve plate disposed between the cylinder block and cylinder head and forming a discharge hole for conducting compressed gas from the compression chamber to the discharge chamber; and a valve apparatus mounted on the discharge valve plate and comprising: a discharge valve including a first fixed end portion and a first elastically movable portion extending from the first fixed end portion for normally lying against and blocking the discharge hole and for being flexed away from the discharge hole under the force of compressed gas in the compression chamber; a stopper valve mounted behind the discharge valve and including a second fixed end portion arranged to press against the first fixed end portion, and a second movable portion extending from the second fixed end portion and against which the first movable portion can abut, to limit the extent of opening of the discharge valve; and a keeper member disposed behind the stopper valve for retaining the stopper valve and discharge valve in place, the keeper member including a third fixed end portion fixed to the discharge valve plate by a fixing pin, and a fourth fixed end portion fixed to the valve plate solely by a pressure force of the cylinder head; the method comprising the steps of:
- (A) providing the discharge valve plate with an accommodation recess and a pin-fixing hole disposed in the accommodation recess, the accommodation recess opening in a direction away from the cylinder block;
- (B) providing the third fixed end portion of the keeper member with a stepped configuration having a first groove formed therein the groove extending from an edge of the third fixed end portion;
- (C) providing the fixing pin with a second groove;
- (D) sliding the second groove of the fixing pin into the first groove of the keeper member and installing the fixing pin into the pin fixing hole to fix the third fixed end portion within the accommodation recess, with the discharge valve and the stopper valve disposed between the keeper member and the discharge valve plate, and with the first and second fixed ends spaced from the fixing pin in a direction toward the discharge hole; and
- (E) installing the cylinder head to the cylinder block in non-engaging relationship with the fixing pin, whereby the cylinder head presses against the fourth fixed end portion of the keeper member.
