Abstract

SUMMARY OF THE INVENTION Pistons are mounted next to each other in a cylinder. The inlet and outlet valves are mounted respectively on the side of the extreme pistons. The pistons are kinematically connected to the drive with the possibility of sequential movement from one extreme piston to the other and are made in the form of concentric rings. The receiver is installed in the cavity of the ring of smaller diameter. The discharge valve is installed on the receiver. 1 C.p. f-ls, 2 ill.

Description

The invention relates to mechanics and can be used in industries engaged in the manufacture of pumps and compressors for fluids. The greatest effect of the invention can be obtained by using it as a compressor.

An object of the invention is to increase the efficiency of a piston machine by improving piston sealing.

In FIG. 1 shows a piston machine, top view; figure 2 - the device of the piston machine, a view in section along the axial line.

A piston machine consists of a cylinder 1 made of metal or other durable material, inside of which three or more pistons 2 are arranged concentrically, made in the form of concentric rings. Pistons 2 can have o-rings - compression rings and a lubrication system. Pistons 2 can be hollow, which reduces their inertia. The lateral surface of the cylinder 1 is equipped with an inlet 3, which together with the piston 2 forms an inlet valve. The receiver 4 is equipped concentrically with the smallest piston 2 and is equipped with a discharge valve 5. The pistons 2 are able to move sequentially from the extreme piston to the other. The pistons 2 are mounted at the top end to a power actuator, which ensures their consistent movement.

The device operates as follows: the initial position in Fig. 2 - all pistons are in the upper position. The cavity of the cylinder 1 under the pistons 2 is filled with a fluid, for example gas. The inlet 3 is open and communicates the internal cavity of the cylinder 1 with a source of fluid. By means of a power drive, the piston 2, which is positioned farthest from the center of the device, is moved. This decreases the volume of the cavity of the cylinder 1 located under the pistons 2. At the same time, the edge of the piston 2 overlaps the inlet 3.

The pressure inside cylinder 1 is increasing. When the extreme piston 2 reaches the lower position, the piston 2 concentrically disposed, which continues to compress the fluid, is set in motion. When this piston 2 reaches the lower point, the extreme piston 2 moves upward, which causes the opening of the inlet 3 and the intake of a new portion of the fluid into the cylinder 1. At the same time, the piston 2 having the smallest diameter starts to move downward. As a result, the pressure of the fluid rises significantly, which facilitates the opening of the discharge valve 5, and the flow of fluid into the cavity of the receiver 4. After that, the extreme piston 2 moves downward, the concentric piston 2 moves upward, etc., i.e. the fluid injection cycle into the receiver is continuous. Possible0
