Description

The present invention relates to the field of compressor engineering, namely, devices for pumping gas of a piston type, and can be used in various sectors of the economy.

A piston-type gas or liquid supercharger is known (see A. G. Kasatkin’s book “Basic Processes and Apparatuses of Chemical Technology”, M .: Alliance, 2005, p. 158, Fig. IV-3a), containing a cylinder with a suction and discharge valves and a piston mounted in the cylinder with the possibility of axial reciprocating movement.

The disadvantages of this supercharger are low productivity due to the small working volume of the cylinder and the complexity of the design and maintenance due to the presence of a complex valve system.

The prototype is a piston gas supercharger (see AS USSR No. 1216423, MKI F04B 31/00, BI No. 9, 1986) containing an open-end cylinder, a discharge tank located coaxially to the cylinder with an inlet in communication with the cylinder side of its open end, and placed in the cylinder piston, the open end of the cylinder is located relative to the tank with a gap.

The disadvantage of the prototype is the low productivity due to getting into the discharge tank not all ejected from the cylinder of the gas stream due to its dispersion before entering the inlet of the discharge tank.

The task of the invention is to increase productivity.

The task is carried out in that in a piston gas blower comprising an open-end cylinder, an injection container located coaxially to the cylinder and an inlet connected to the cylinder from its open end, and a piston located in the cylinder, the open end of the cylinder is positioned relative to the container with a gap, according to between the discharge tank and the cylinder, a discharge pipe is installed coaxially arranged with a gap both relative to the discharge tank and relative to the cylinder, moreover, Tr of the discharge pipe is larger than the diameter of the cylinder and less than the diameter of the discharge tank.

The drawing shows a diagram of a piston gas supercharger.

The piston blower comprises a cylinder 1 with an open end 2, a piston 3 placed in the cylinder with the possibility of axial reciprocation, and located coaxially to the cylinder and with a gap relative to its open end, the discharge tank 4 with the inlet 5. Between the cylinder 1 and the discharge tank 4 a discharge pipe 6 is installed, coaxially located to the cylinder, with a gap of 7 relative to the cylinder and with a gap of 8 relative to the discharge tank.

The diameter of the discharge pipe 6 is larger than the diameter of the cylinder 1 and less than the diameter of the discharge tank 4.

The supercharger operates as follows.

The piston 3 performs an axial reciprocating motion in the cylinder 1, while the piston stroke length is much less than the cylinder length. If the frequency of the forced oscillations of the piston 3 coincides with the frequency of natural vibrations in the gas cylinder 1, due to the phenomenon of resonance, periodic shock waves arise in the cylinder, and portions of gas are ejected from the cylinder through its open end into the discharge pipe 6. Since the diameter of the discharge pipe 6 is larger than the diameter cylinder 1, the gas jet leaving the cylinder will fully enter the discharge pipe. At the same time, as a result of ejection through the gap 7 between the discharge pipe 6 and the cylinder 1, gas will rush into the discharge pipe from the space outside the cylinder. From the discharge pipe 6, gas is ejected through the inlet 5 into the discharge tank 4. Since the diameter of the inlet 5 of the discharge tank 4 is larger than the diameter of the discharge pipe 6, the gas jet leaving the discharge pipe completely enters through the inlet 5 into the discharge tank 4. At the same time, as a result Ejection through the gap 8 between the discharge tank 4 and the discharge pipe 6 into the discharge tank rush gas from the space outside the discharge pipe.

Feasibility from the use of the invention is achieved by increasing productivity. This became possible due to the placement between the cylinder and the discharge tank of the discharge pipe coaxially located with the cylinder and with a gap both relative to the discharge tank and relative to the cylinder, and the diameter of the discharge pipe is larger than the diameter of the cylinder and smaller than the diameter of the discharge tank.
