Description

Known hydropneumatic valve, consisting of a valve and a saddle.

The proposed hydropneumatic valve is characterized in that the angle of the sharp edge of the saddle is selected in accordance with the ratio

Hydropneumatic valve has a tapered locking body / and saddle 2 (see drawing).

When the valve operates, due to the force created by the locking organ, the metal of the sharp edge is crushed to form a pad of length a, which compensates for the non-circularity of the hole, characterized by size D.
