Abstract
The invention relates to an on-off valve with a pressure reducer intended to be connected to a gas cylinder. The objective of the invention is to ensure that the device is closed and put into service by way of simple and reliable means at high pressures. A shutter is controlled by a mobile part of the valve with pressure reducer, forming a low-pressure chamber of the device. The shutter is subjected to an elastic force in the closing direction. A working spring of the valve with pressure reducer acts on the mobile part in the opening direction. A rotary control member working over at least one turn makes it possible to compress the working spring into the position in which the valve with pressure reducer is put into service. In the closed position, a plate of pusher of the control member is remote from the working spring.
