ABSTRACT:
A two-stage reduction valve for gaseous fluids consists of a high-pressure assembly with a high-pressure diaphragm (10) actuating a valve member disposed in the throat of a gas cylinder and of a low-pressure assembly with a likewise diaphragm-operated valve member (21) positioned in a gas duct (18) extending from the high-pressure assembly. A closing rod (30) connected with an operating handle (41) is restrictedly displaceably connected with a diaphragm spindle (14) firmly connected with the high-pressure diaphragm (10) and has at its upper end an essentially cylindrical bore (43) to displaceably receive the lower end of the closing rod (30). The upward circular mouth (44) of the bore (43) has a reduced diameter and the closing rod (30) has at its lower end a head (45) with a width larger than said reduced diameter but with such a shape that it may be inserted into the bore (43) through the mouth (44) of the bore with the closing rod (30) inclined in relation to the axis of the diaphragm spindle (14), but when inserted it is prevented from being pulled out from the bore.
