<p>The valve has a housing (1) with a seat (3) against which the valve is supported, carried by the valve carrier (5) and pushed by a spring (6), with a regulator (7) controlling spring tension. The valve can be lifted off its seat by an exterior manual rod (12) which crosses the head (2) of the valve closing the body. Axial play is provided between lever (11) and valve carrier at the level of the junction between the carrier and the interior end of the rod, and the recall spring transmits a push on carrier without working on the rod.</p> |
