出室5b側へ吐出される。Next, the operation will be described. During the intake stroke in which the piston 2 descends in the cylinder 1a, the pressure in the cylinder 1a becomes lower than the pressure in the intake chamber 5a and the intake passage 4a, and the pressure difference causes the intake valve 3 to deform toward the cylinder 1a side. The refrigerant gas is sucked into the cylinder 1a from the suction chamber 5a through the suction passage 4a. And the piston 2 is a cylinder
In the compression stroke that rises in 1a, the internal pressure of the cylinder 1a gradually increases, the suction valve 3 is fully closed, and the internal pressure of the cylinder 1a is applied to the discharge valve 7 and the pressure in the discharge chamber 5b When it becomes higher than the spring force of the valve spring 8 pushing the valve 7, the valve spring 8 is deformed and the discharge valve 7 is opened to open the cylinder 1a.
The compressed refrigerant gas therein is discharged to the discharge chamber 5b side through the discharge passage 4b and the discharge hole 6a.

果、吐出弁７の抑えができなくなるという課題があっ
た。Since the valve device in the conventional refrigerant compressor is configured as described above, the discharge valve 7 and the valve spring 8 are not fixed to any of them during the operation of the compressor, so that they easily rotate. For this reason, since the valve spring 8 is in contact with the receiving surface of the valve retainer 9, the outer peripheral edge of the valve spring 8 is worn and becomes thin, and eventually cracks or the like occur, so that the valve spring cannot operate. There is a problem that the discharge valve 7 cannot be suppressed.

ある。A refrigerant compressor valve device according to the present invention comprises an annular or circular discharge hole formed by a valve plate and a valve receiving member, a discharge valve located on the discharge hole and normally closed, and a discharge valve The valve retainer for regulating the levitation amount and the curved plate-shaped valve spring that is inserted between the discharge valve and the valve retainer and biases the discharge valve toward the discharge hole. A belt-shaped sloping inclined surface for restricting the rotation of the valve spring is formed on a part of the surface.
この考案においては、弁押えの弁受け面を弁ばねの形状
に沿った傾斜湾曲面としたので、弁ばねの回動が規制さ
れ、該弁ばねの回動摩耗による破損が防止できる。In this invention, since the valve receiving surface of the valve retainer is an inclined curved surface that conforms to the shape of the valve spring, the rotation of the valve spring is restricted, and damage due to rotational wear of the valve spring can be prevented.

FIG. 2 is a sectional view of a valve device of a refrigerant compressor according to the present invention,
The figure shows an inner view of the valve retainer. The present invention differs from the valve device of the conventional example in that a strip-shaped sloping inclined surface 9a is formed so as to cross the center of a part of the valve receiving surface of the valve retainer 9. Since the other parts are the same as those of the conventional example, the same reference numerals are given and the description thereof is omitted.

ことはない。Since the valve device of the present invention is configured as described above, since the rotation of the valve spring 8 is restricted by the raised inclined surface 9a of the valve retainer 9, the wear between the valve spring 8 and the valve receiving surface is reduced, Therefore, the valve spring 8 is hardly damaged due to wear.
