Description

The invention relates to pneumohydromashinostroenie and can be used in various sectors of the national economy in the actuators, pneumohydraulic-driven pumps and other objects of technology.

The purpose of the invention is to extend the functionality by drastically vacuuming the chamber.

The drawing shows a diagram of a device for pumping fluid.

The device consists of a sealed housing 1, in which a drum 3 with a sleeve 4 wound on it is connected to the shaft 2 connected to the engine. The end 5 of the sleeve 4 is unscrewed and fixed in the pumping cavity 6, which is connected to the hydraulic line 8 via valve 7 pumped medium near the bottom of the cavity bis

a limited volume chamber 9 is located near the fixing point of the end 5 of the sleeve 4 in the pumping cavity 6. The sealed body 1 communicates with the supply medium 5 through the valve 10 through the valve 12 of the preliminary evacuation line 13 to the pumping cavity 6 in its distant peripheral part. The chamber 9 of a limited volume is connected to the pumping cavity 6

0 through the pipe 14. Pump cavity 6 is connected to the atmosphere by valve 15.

The device works as follows. The shaft 2 rotates from the engine and coils a hose 4 on the drum 3, which is discharged from the pumping cavity 6. In the last 5, a vacuum is formed which is transmitted to the pre-vacuum line 13. Upon further progress of the sleeve 4, the nozzle 14 of the chamber 9 of a limited volume opens and the pumped medium enters the

pumping cavity 6. When winding a hand-When valves 7 and 15 are closed with a namava 4, the medium filling its cavity is pulling the sleeve 5 onto the drum 3 in the pump room

it is led to the atmosphere through the valve 10. A vacuum is created in the coh cavity, which creates the sleeve 4 completely wound around the bar-s and in line 13 of the pre-waban 3, into its cavity a working Zumouri is fed. At the end of the course of the flexible sleeve

the medium that re-inserts the sleeve 4 into the pump-opening of the nozzle 14 and in the chamber 9 the cut cavity 6, displacing the pumped volume from it, creates a sharp permitted medium into the main line 8. reduction.

Claims (2)

1. A device for pumping a fluid medium, comprising a housing in which an elastic membrane is installed with the formation of the drive and pump cavities, made in the form of a flexible sleeve wound on a drum connected to the engine, the free end of which is turned inside out and fixed around the perimeter on the wall of the housing moreover, the drive cavity is in communication with the fluid supply system and through the valve with the atmosphere, and the pump cavity is in communication with the hydraulic line of the pumped medium, characterized in that, in order to expand the functionality In the area of fastening of the flexible sleeve from the side of the pump cavity, a pipe is made on the body that is connected to the chamber of limited volume, and the pump cavity is additionally communicated through the valve to the atmosphere. 2. The device according to π. 1, characterized in that the pump cavity is in communication with the pre-evacuation line.
