Abstract

PURPOSE:To shorten the distance between a compression chamber and a delivery valve for increasing the compression efficiency, by bending both ends of a valve retainer at right angles, and inserting this valve retainer into a delivery valve chamber as both ends of the valve retainer are pressed against the delivery valve chamber wall which is opposed to a compression chamber. CONSTITUTION:A reed valve 12 whose center is fixed with a rivet, is set in a delivery valve chamber 10 which is surrounded with side boards 7, 8 and the cylinder 9 of a rotary compressor. Both ends of a valve retainer 11 of said reed valve 12 are bent at right angles, and inserted into the delivery valve chamber 10 as they are pressed against the delivery valve chamber 11 which is opposed to a compression chamber 6. In this way, the distance between the compression room and the reed valve can be shortened, because it is not necessary to fix the reed valve with a bolt. Consequently, the compression efficiency can be increased.

記ローラ５で囲まれている。In FIG. 1, 1 is an airtight container, 2 is a motor stator fixed in the airtight container 1, 3 is a rotor, 4 is a crankshaft rotated by the rotor 3, and 5 is the crankshaft. This is a roller that compresses the refrigerant using an axial force of 4. A compression chamber 6 is surrounded by an upper end plate 7, a lower end plate 8, a '1jfcFt5 body 9, and the roller 5.

ている。In FIG. 2, it is a discharge valve chamber provided in a 10 bmJ gas cylinder body. The valve holder 11, the valve 12, and the valve seat 13 are fastened with rivets 14 and inserted into the discharge valve chamber 10.

圧縮室６で圧縮された冷媒は吐出孔１５を通り、前記弁
１２を押し上げて、前記吐出弁室１０に吐出される構成
になっている。The refrigerant compressed in the compression chamber 6 passes through a discharge hole 15, pushes up the valve 12, and is discharged into the discharge valve chamber 10.

上記構成において、前記弁押え１１は、両端を直角に曲
げその端面を前記圧縮室６と反対側の吐出弁室壁に圧接
させている。In the above configuration, both ends of the valve holder 11 are bent at right angles, and the end surfaces thereof are brought into pressure contact with the wall of the discharge valve chamber on the opposite side from the compression chamber 6.

従って、弁押え１１のバネ力でもって、前記弁１２、弁
押え１１、弁座１３は、吐出弁室に固定−されている。Therefore, the valve 12, valve holder 11, and valve seat 13 are fixed in the discharge valve chamber by the spring force of the valve holder 11.

また本発明の弁押え購造は、ボルトにより気筒体に固定

By assembling the valve holder with a fastening member, bending both ends of the valve holder at right angles, and inserting the valve holder in pressure contact with the wall of the discharge valve chamber on the opposite side of the compression chamber, the spring force of the valve holder can be used to tighten the valve and the valve holder. , the valve seat can be fixed at the discharge valve pressure. Also, since no bolts are used, it can be easily inserted into the discharge valve chamber. The distance between the compression chamber and the discharge valve chamber can be shortened, the volume of the discharge hole can be reduced, and the efficiency of the compressor can be improved.
