Abstract

The invention can be used in compressors with oscillating working elements. The purpose of the invention is to reduce the size of the compressor. In the cylindrical bore of the housing 1 with end caps 2 stationary partitions (P) 3,4,5 are placed. The pistons 6 are mounted on the working shaft 7 in the cavity of the housing 1 and form working chambers 8 with the P3,4,5. The shaft 7 is connected with the output shaft 9 by a crank and connecting rod mechanism 10. In the P4 mounted coaxially to the shaft 9, there is a through axial passage ( K) 11 communicated with the outlet K12 of the casing 1. In P3.5, the inlet K13s are made. On the shaft 7 on the side K12 there is an interfaced with the inner surface P4 with the possibility of angular movement of the arc plate 14. On the outer cylindrical surface of the plate 14 are grooves 15 having the possibility of alternately communicating with K12. The covers 2 are provided with bypass K16 for communication of chambers 8 with K13. The mechanism 10 is placed in the cavity of the housing 1. 1 Il.

The invention of OTHOcnTdH to mechanical engineering, in particular to compressors with oscillating working elements.

The aim of the invention is to reduce the size of the compressor.

The drawing shows a compressor longitudinal section.

The compressor includes a housing 1 with end caps 2, in a cylindrical bore of which three fixed partitions 3-5 are placed evenly around the circumference. The pistons 6 are mounted on the working shaft 7 in the cavity of the housing 1 and form a bfH 3-5 working chambers 8. The working shaft 7 is connected to the output shaft 9 by a crank-and-connecting rod mechanism 10. In the partition 4, mounted coaxially with the output shaft 9 , a through axial channel 11 is provided, communicated with the outlet channel 12 of housing 1, and the inlet channels 13 are filled in the partitions 3 and 5. On the working shaft 7 on the side of the exhaust channel 12 there is an interface with the inner surface of the partition 4 and possibly HOCTbk of arc angular displacement pad 14 with performed on its outer cylindrical surface with grooves 15 and with the possibility of alternately communicating the latter with the exhaust I channel 12. In the end caps 2, the overflow channels 16 are internally attached to communicate the working chambers 8 with the inlet channels 13, while the crimp-connecting rod mechanism 10 is placed in the housing cavity 1. The working chambers 8 between the pistons 6 and the bulkheads 3 and 5 form the first compression stage and the working chambers 8 between the pistons 6 and the partition 4 - the second compression stage.

The compressor works as follows.

When the shaft 9 is rotated, the crank mechanism 10 causes the pistons 6 to swing, while

the gas entering the working chambers 8 is compressed in stage I. With further rotation of the shaft 9 compressed gas through the bypass channels 16 enters the working chambers 8 II stage, where it is squeezing and then inlet through the grooves 15 lining 14 into the exhaust channel 12 of the housing 1.

This embodiment of a two-stage compressor leads to a decrease in its dimensions.

Claims (1)

Invention Formula A compressor, comprising a housing with end joints, in the cylindrical bore of which there are placed non-movable partitions, pistons mounted on the working shaft in the housing cavity, forming working chambers with partitions with the output shaft, and the working shaft connected to the output shaft and exhaust channels, which are distinguished by the fact that, in order to reduce overall dimensions, at least three fixed partitions are placed evenly around the circumference in the housing, in one of which, mounted coaxially with the output shaft, not through axial channel, communicating with the outlet channel of the body, and in other partitions inlet channels are made on the working shaft with. the sides of the outlet channel are placed adjacent to the inner surface of the partition and the possibility of angular movement of the arc plate with grooves made on its outer cylindrical surface with the possibility of alternately communicating the latter with the outlet channel, in the end covers from the inner side there are overflow channels for communicating working chambers with Inlet channels, opposite to this crank mechanism, are located in the housing cavity.
