Abstract

PURPOSE:To reduce the noise accompanying the contact of a reed valve with a valve seat in a device in which the reed valve is overhung in a valve seat body in which a delivery port is formed, by making the lift at the free end of the reed valve lower than the lift at the area corresponding to the delivery port. CONSTITUTION:In a valve seat body 3 is formed a delivery port 6, around which a valve seat 10 is provided. A reed valve 19, which opens and closes the delivery port 6, is formed in a segment form and held on the valve seat body 3 with a fixing member 9, bent against the seat body 3. In this case, the lift of the free end of the reed valve 19 is made lower than the lift of its part corresponding to the delivery port 6 by providing a draw-out stopper 20a with a sliding long hole member fitted in the tip area of a holder 20 provided on the valve seat body 3. Thereby the contact of the reed valve 19 with the delivery port 6 can be distributed to make soft riding to reduce the vibration of the reed valve 19 and the valve seat body 3 and thus decreasing the valve sound and noise.

Reed valve devices are generally used in compressors, internal combustion engines, and the like. A reed valve device automatically opens and closes a thin plate-shaped reed valve by bending it under pressure, and is used in a wide range of applications because of its simple structure. In the compressor, as shown in FIG. 1, a reed valve device is used to discharge the refrigerant compressed within the cylinder 2 by the eccentrically rotating roller 1 to the outside of the cylinder 2. That is, roller 1
is eccentrically rotated via a crank part 5 by a shaft 4 rotatably supported by a main bearing 3, and a discharge boat 6 is attached to the main bearing 3, as shown in FIG. A reed valve (discharge valve) 7 for opening and closing the discharge boat 6 is attached together with a valve stopper 8 by a fixture 9 in a cantilevered manner. A valve seat 10 is formed on the periphery of the discharge boat 6 and acts to close the discharge boat 6 by coming into contact with the reed valve I. These discharge boat 6, reed valve 7, valve stopper 8, valve seat 10, etc. constitute a reed valve device. Its function is that when the pressure of the compressed refrigerant in cylinder 2 exceeds a certain value, the reed valve γ is bent by that pressure, lifted and opened, and when the pressure decreases, it returns to its original state and closes. By this, the refrigerant at a predetermined pressure is
The liquid is discharged into a valve cover 11 as shown in the figure. Regarding the refrigerant discharged into the valve cover 11,
It flows into the through hole 12 of the cylinder 2 as shown by the arrow, then flows along the inner surface of the casing 13 as shown by the arrow, and flows out from the discharge pipe 14. In addition, the casing 13
The refrigerant flows into the shaft through the suction pipe 15, and the reciprocating motion of the blade 16 is used to supply lubricating oil to the sliding parts. The oil is sent to various places through the 18-karat gold hole provided.

At the moment when the discharge is completed while floating 21M, cylinder 2
Because the reed valve 7 and the valve seat 10 collide with each other, the reed valve 7 and the main peg 3 vibrate, causing a lot of noise.

This relationship is based on experimental measurements, as shown in Figure 3, where the change in cylinder pressure and the change in noise level occur in the same cycle, and the noise level is at its maximum when the cylinder pressure is at its lowest, which corresponds to when the reed valve 7 lands. This is confirmed by the results. Since noise leads to environmental destruction, there is a wide demand for low-noise reed valve devices.

When the pressure of the discharge boat 6 further increases, as shown in FIG. 8, the free end of the reed valve 19 collides with the stopper 20a at the tip of the support 2o, preventing it from rising. The part facing the boat 6 is pushed up, and finally becomes higher than the lift at the free end and turns over.
The opposite side now faces the valve stopper 8. After this,
When the pressure in the discharge boat 6 suddenly decreases, the reed valve 1
9 will be strongly attracted to the discharge boat 6,
Since the opposite side faces the valve stopper 8, first, only the free end of the reed valve 19 lands on a part of the valve seat 10 as shown in FIG. part lands on the other part of the valve seat 10, and at that time, the reed valve 1
9 is reversed so that the other side faces the valve seat body 3, and the fourth
As shown in the figure, the discharge boat 6 is closed. In this case, the free end of the reed valve 19 lands on a part of the valve seat 10, and then the remaining part lands on the other part of the valve seat 1o.
Since it is a stepwise operation, the impact between the reed valve 19 and the valve seat 10 is dispersed in each step, and the landing of the reed valve 19 on the valve seat 10 results in soft riding, causing the reed valve 1″9 and the valve seat body 3 The vibration of the valve is reduced.Therefore, the valve sound is reduced and noise can be reduced.
