Abstract

The invention relates to mechanical engineering and can be used in medical technology as a vacuum pump. The purpose of the invention is to ensure the sterility of pumping the working medium. The operating member 4 forms with the housing 1 a working cavity 7 and is connected with the actuator 9 of reciprocating movement. In the body 4, the bypass channels 10, 11 are made, in which the bypass valves 12 with shut-off elements are installed 13. The body 4 is made in the form of two membranes 5 with a common rigid center 6, one of which forms with the body 1 a working cavity 8. The element 13 in the form of a ball 14 mounted on a perforated membrane 15, as well as bypassing channels from cavities 7.8, makes it possible to avoid contact of the pumped medium with the process fluid. 1 il.

The invention relates to compressor and vacuum engineering and can be used in medical technology as a vacuum pump for pumping sterile media.

The working medium from the working cavity 7 with the injection pressure flows through the holes in the perforated membrane 15 into the overflow channel 11.

The purpose of the invention is to provide a channel 10 and close the channel 11 of the working fluid transfer rate of the opposite bypass valve 12.

The drawing shows a schematic diagram of the supercharger.

The supercharger includes a housing 1 with a vasa due to the transition of the locking element 13 under the action of inertial forces, increasing at the approach to the m. from the upper saddle to the lower 2 and injection 3 clings. During the transition time of the shut-off valve, the working body 4, made by vent 13 from one saddle to another, the working medium from channel 11 flows through the holes in the perforated membrane 15 into the working cavity 8, where two membranes 5 with a common rigid
