VALVE MECHANISM FOR PNEUMATIC WEAPON Russian patent published in 1997 - IPC

FIELD: pneumatic small arms. SUBSTANCE: sealing element 4 is made in the form of a flat ring and placed in an annular groove of body 2. Formed at end 9 of valve 1, facing the sealing element, is a seat with flat bottom 11 that is engageable with body 2 in the area of outlet 3. Valve end 9 can be engaged with sealing element 4. The thrust of bottom 11 against the annular shoulder of body 2 limits the deformation of sealing element 4 by the flexible zone, which enhances the service life of the sealing element on the whole.
