| 摘要 |
<p>The invention relates to a pressure reducer for compressed gas, comprising a high-pressure chamber (10) which is accommodated in a body (1) and which is to be connected to a compressed-gas tank, a low-pressure chamber (15) for receiving the gas, the pressure of which has been reduced, a valve (70), a pipe (17) connecting the high-pressure chamber (10) to the low-pressure chamber (15), the valve (70) being accommodated in the high-pressure chamber and bearing against a seat (750) at the outlet of the pipe (17) into the high-pressure chamber (10), a push member (74) accommodated in the low-pressure chamber (15) and contacting the valve (70) through the pipe (17), and balancing means (71, 72, 73) engaging with the valve (70) via the push member (74) depending on the pressure in the low-pressure chamber (15). The valve (70) comprises a stem (702) having a cross-section that is equivalent to that of the pipe (17) in the area of the seat (750), the stem (702) extending just into a compensation chamber (77) that is sealingly separated from the high-pressure chamber (10).</p> |
