Description

one

This invention relates to a KOMnpecc construction and relates to piston compressors.

Closest to the present invention is a piston compressor containing a cylinder and a piston installed in it with a shutter, the cavity of which is connected through a non-return valve with a compression chamber and with a gap in the capillaries in its side wall 1}

Onako this piston koMnpeccqp has not enough high efficiency.

The purpose of the present invention in-. The efficiency of a piston compressor increases.

This goal is achieved. In the piston cavity there is a valve equipped with throttle holes, the last section is divided into two chambers, while the chamber located further from the compression chamber is connected with capillaries through the walls of the piston, and the cylinder is equipped with with a casing, with its wall, having from the side of the gap evenly located along its surface capillaries, a shirt filled with liquid and communicated by pipeline with a source of liquid and using capillaries and channels, in the wall of the basin with a gap.

The drawing schematically shows the proposed piston compressor, a longitudinal section.

The piston compressor contains a cylinder 1 and a piston 3 installed with a gap 2, the cavity of which is connected to a compression chamber 5 through a non-return valve 4 and with a gap 2 in the capillaries 6 in its side wall. At the same time, a partition 8 is installed in the cavity of the piston 3, which is equipped with throttle holes 7, separating the latter into two chambers 9 and 10, respectively, and a chamber 9 located further from the compression chamber 5, via channels 11, made in the wall of the piston 3, are communicated. with a capillary 6, with a wall 13, with a capillary 14 on the side of the gap 2 that has evenly spaced capillaries 14 on it, a shirt 15 filled with liquid and communicated with a source of liquid 16 by a pipe (not shown ) and with the aid of the capillaries 14 and the channels 17, made in the wall 13 of the cylinder 1, with a gap 2. The cylinder 1 is equipped with a suction and discharge valve 18 and 19.

Piston compressor operates as follows.

The working gas through the suction valve .18 enters the compression chamber 5, where it is compressed by the piston 3 and is pumped to the consumer through the valve 19. Part of the working gas from the compression chamber 5 through the check valve 4 enters the chamber 10 and then through the throttle openings 7 into the chamber -9 and then through channels 11 and capillaries 6 - into gap 2, creating a carrier gas layer in it, which prevents Porsch 3 from touching sgtenka 13 of shshindra 1. Liquid under pressure flows through pipeline 1b-B to jacket 15 and then through channels 17 and capillaries 14 into the gap 2, creating in it. liquid-layer, reducing the cross section of the gap and reducing leakage of compressible gas.

At the beginning of the stroke, the piston 3 upwardly centers the piston mainly by the liquid carrier layer, since the pressure in chamber 9 decreases and the pressure of the gas entering the gap 2 through channels 11 and capillary 6 decreases, and the layer of liquid entering the gap 2 through channels 17 and the capillaries 14, is increased, ensuring the centering of the portions 3 in cylinder

1. At the end of the stroke of the piston 3 up and when it moves downward, the centering of the piston is carried out predominantly by a gas carrier layer, since the pressure in the chamber 9 rises, consequently, the pressure of the gas entering the

the gap through the channels 11 and the capillaries 6, and the latter displaces the liquid from the gap 2, preventing its flow into the gap 2 through the capillaries 14.

When approaching the bottom dead center, the pressure in chamber 9 decreases so much that the gas flowing out of it is no longer able to completely force the liquid out of the zoeor 2 and the filling of this gap with liquid begins. Then the cycle is repeated.

Thus, such a design, a piston compressor can reduce the temperature of the parts of the piston.

group, allows you to work at smaller gaps and reduce leakage and gas consumption to center the piston during its downward motion, which ultimately reduces the loss of compressor power

centering and increase efficiency.
