SU1644104A1 - Pressure regulator for compressed gas vehicles - Google Patents

Abstract

The invention relates to mechanical engineering. The purpose of the invention is to reduce gas consumption and toxicity of exhaust gases by regulating the gas supply depending on the engine operation mode. The pressure regulator for gas cylinders is a two-stage membrane-lever reducer. The throttle valve is new through the tongue pusher stem of the membrane of the first stage, the adjusting nut which is provided with an emphasis for the membrane spring 1 sludge.

Description

The invention relates to mechanical engineering and can be used to reduce the pressure of the working medium in the power supply system of gas cylinders.

The aim of the invention is to reduce the gas consumption and the toxicity of exhaust gases by regulating the gas supply depending on the mode of operation of the engine with

The drawing shows a diagram of the regulator

The pressure regulator includes a housing 1, a cavity 2 of the first stage, an inlet channel 3 that overlaps the first valve 4, kinematically connected with the first membrane 5 mounted on the rod 6, the cavity 7 of the second stage with the output channel 8 "The cavity 7 of the second stage connected to the cavity 2 of the first stage through the second valve 9 connected through a lever

10 with the rod AND the second membrane 12 ,. In the cavity 7 of the second stage is located the discharge device 13, which creates an additional force on the membrane 12.

The membrane 5 is spring-loaded by a spring 14, the varying force on the membrane 5 by means of an adjusting nut 15, made with an emphasis 16. On the rod 6 of the membrane 5, a pusher 17 is rigidly mounted with a thrust washer 18 and a volume 19 o On top of the regulator, in the area of the first stage, two bracket 20, in which axis 21 rotates with tongue 220 axis 21 through levers 23 and 24 and THFV 25 is connected to axis 26 rotating by brackets 27 which are fixed to the engine; axis 26 is connected to pi with pinwara 28 throttle control (not shown) „

The cavity of the discharge device 13 is connected to the intake manifold 30 of the engine. In the case of the band 7 of the second stage, the nozzle 31 of the output channel and the nozzle 32 of the gas outlet of the metering and economizer device 33 are made

The pressure regulator works as follows.

Regulate the first stage to a pressure of 0.01-0.02 MPa "This pressure is enough for the engine to work stably in idle mode

while minimizing toxicity with increasing speed

engine gas (increase throttle opening) due to the system tg 25 and 29 and the levers 23, 24 and 28 pivot the axle 21 with the latch 22 acting on the pusher 170 Moving down, the pusher 17 through the pin 19 and the thrust washer 18, mounted on it, compresses the spring 14 of the membrane 5, which transmits the resulting force to the valve 4, with which it is connected kinematically. When the gas supply decreases, so that the accelerator pedal pressure is reduced, the spring 14 is compressed through the thrust washer 1 and the pin 19 raises the pusher 17, respectively, the diaphragm rod 6 rises. As a result, the flow area of the valve 4 decreases and the pressure in the cavity 2 decreases. steps

The valve 9 of the cavity 7 of the second stage works without changes. When the engine is started up, a vacuum is created in the intake manifold, which is transmitted to the cavity of the unloading device 13. The unloading device 13 bends and unloads the membrane 12.

idle

The second stage of the regulator, the valve 9 opens, and the gas first fills the cavity 7 of the second stage of the regulator, and then through the nozzle 31 of the system and the nozzle 32 of the metering and economizer device 33 to the engine. As the throttle valve opens, engine cylinders increase.

The use of a regulator allows to reduce gas consumption and exhaust gas toxicity, especially in mode.
