Abstract

The invention can be used in compressors with electric drive from linear electric motors. The purpose of the invention is to increase the service life and increase the efficiency of a piston compressor. Pistons rigidly connected to the rods are mounted in cross-shaped cylinders. The cordless synchronization mechanism includes a crank shaft mounted rotatably with respect to the housing and perpendicular to the axles of the cylinders. On the neck of the shaft there is a double eccentric, each cam of which encloses a holder rigidly connected with the rod of the corresponding piston. The drive is made in the form of linear asynchronous motors mounted coaxially and symmetrically with respect to the axis of rotation of the shaft. The stators are mounted on the case. The rotors are rigidly connected with additional rods to the corresponding holder of the synchronization mechanism. 2 Il.

The invention relates to compressor building and can be used in electrically driven compressors from linear electric motors.

The purpose of the invention is to increase the service life and increase efficiency.

FIG. 1 shows the proposed compressor, a general view; 2 is a section A-A in FIG. one.

The piston compressor includes a housing 1, cylinders 2 and 3 located crosswise, pistons 4 and 5 installed in cylinders 2 and 3 and rigidly connected to the rods 6 and 7, a drive and a strapless synchronization mechanism including a perpendicular mounted rotatably relative to the housing 1 and Rno to axle cylinders

2 and 3 crank shaft 8 on the neck 9 of which is installed a double eccentric 10, each cam 11 and 12 of which covers the cage (13 and 14) rigidly connected with the rod (6 and 7) of the corresponding piston (4 and 5). The drive is made in the form of linear asynchronous motors 15 and 16 installed coaxially and symmetrically with respect to the axis of rotation of the crank shaft 8 to each cylinder 2 and 3, while the stators 17 and 18 of the engines 15 and 16 are fixed to the housing 1, and the rotors 19 and 20 are rigidly connected additional rods 21 and 22 with the corresponding yoke 13 and 14 of the synchronization mechanism.

At the same time, the rods 6 and 7 and additional rods 21 and 22 are installed respectively. Respectively in guides 23-26, cams 11 and 12 of double eccentric 10 are connected to neck 9 of crank shaft 8 by means of rollers 27 and 28, and clips 13 and 14 by means of rollers 29 and 30. Cylinders are sealed by covers 31 and 32 s suction and discharge valves 33 and 34.

The compressor works as follows.

The voltage applied to the windings of the stators 17 and 18 in a given queue

nosti. The magnetic flux causes the rotors 19 and 20 to make a reciprocating movement. While the rotors.19 and 20 provide through additional rods 21 and 22 of the clips 13 and 14 and the rods 6 and 7, the reciprocating movement of the pistons m 4 and 5, which in turn suck and pump gas in the hydraulic cylinders 2 and 3.

In the proposed compressor, the force is transmitted from the drive to the pistons 4 and 5 through tight coupling of the rotors 19 and 20, respectively, with the clips 13 and 14, the rods 6 and 7, and the pistons 4 and 5. The parts of the connecting rod-free synchronization mechanism perform mainly the synchronizing function and almost do not participate in the transmission of forces from the actuator to the pistons m 4 and 5.
