Abstract

The invention allows to increase the compensation capacity of the refrigeration compressor. The motor-compressor frame 4 is connected via a spring 3 to an element 2 rigidly mounted on the casing 1. The intake gas supply compensation pipe is made of links installed with the possibility of vertical movement relative to each other. One of the links is made in the form of an elastic pipe 6, covering the spring 3. The other two links are made in the form of channels 9,10 in element 2 and frame 4, interconnected by an internal cavity of pipe 6. Spring 3 and pipe 6 provide the motor-compressor mobility any plane. 1 il.

(C) DEVICE FOR DIRECTION OF THE ABSORBATED GAS IN A SEALING REFRIGERATING COMPRESSOR

(57) The invention allows to increase the compensating capacity of the refrigeration compressor. The frame k of the motor-compressor by means of a spring 3. is connected with an element 2 rigidly fixed to the casing 1. The suction gas compensation pipe is made of links installed with the possibility of vertical movement relative to each other,. One of the links is made in the form of an elastic pipe 6, covering spring 3. The other two links are made in the form of channels E, Yu in element 2 and frame k, which are interconnected by the internal cavity of pipe 6. Spring 3 and pipe 6 provide for the motor-compressor mobility in any plane. 1 il.

The invention relates to hermetic refrigeration copressors with suction pressure and circulating oil cooling in the casing, which are installed mainly in household refrigeration devices.

A refrigerating compressor with a motor-compressor installed vertically in a casing with a vertical instrumentation break-in and an intake pipe made up of links connecting the gas inlet into the casing with a motor compressor, the suction pipeline being parallel to the motor compressor. Link pipeline provide axial movement of the motor-compressor. The pipeline links are installed with damping sealing elements (German patent N 2650937, class F 25 B 31/02, published 1976).

The disadvantages of this design

the low mobility of the resiliently mounted motor compressor and the associated increased susceptibility to damage under conditions that cause the compressor to oscillate.

. The purpose of the invention is to increase the compensation ability.

The essence of the invention is that the hermetic refrigeration compressor with a vertically located drive shaft of the motor-compressor intake gas enters the compressor cylinder through the attachment element of the compressor unit to the casing and the elastic fastening element of the compressor unit surrounded by a sheath of elastic material. The advantage of the proposed device is to provide the mobility of the compressor unit in any plane. The drawing shows the proposed device.

A device for directing the intake gas in a hermetic refrigeration compressor with a vertically mounted drive shaft of a motor-compressor, the frame of which is connected by means of spring 3 to element 2 fixed on koi (ear 1) contains a compensating pipeline for supplying intake gas to the compressor, made of links, mounted with the possibility of vertical movement relative to each other. One of the links is made in the form of an elastic pipe 6, which covers the spring 3, while

the other two links of the pipeline are made in the form of channels 9 and 10 in the element 2, rigidly fixed on the casing 1, in the frame and communicated with each other by the internal cavity of the elastic nozzle 6.

The channel 9 in the element 2 may have a knee-like shape with horizontal and vertical sections (not shown), with an opening 8 at the junction of the channels, connecting the channel 9 with the housing cavity. Channel 10 may be communicated with a cylinder (not shown) of the compressor through a silencer 5.

The device works as follows.

When the compressor runs, the refrigerant is sucked into the channel 9 of the element 2 and the passage through the internal cavity of the element 6 and the channel 10 in the frame k enters the compressor cylinder through the silencer 5. At the same time, the oscillations of the motor-compressor do not affect the efficiency of the suction process, as the spring 3 and pipe 6 provide the motor-compressor mobility in any plane. I

The oil particles, which are enclosed by the agent, pass a horizontal section of the channel 9, hit the wall of the vertical section of the channel 9 and flow into the cavity of the casing 1 through the opening 8.
