TAPPER VALVE Russian patent published in 2012 - IPC F16K17/36 

FIELD: machine building.

SUBSTANCE: tapper valve contains a pipe with an end wall and an annular groove in the side wall of the pipe near its end wall to form an annular flange located at the inlet housing and fixed relative to the housing and the piston actuator with plunger. The drive is mounted on the wall of the housing and is communicated with a source of pressure and triggering device. In the wall of the housing above the end wall of the pipe a hole is made. The latter contains the plunger lip. On the to the wall of the valve body opposite to the plunger, on its external side a box-trap is attached. In the wall of the housing the window slit is made for the passage of the end wall of the pipe into the box-shaped trap, which is equipped with an end wall locking. The locking is made in the shape of a leaf spring attached to the side of the box trap. The unfixed part of the leaf spring is located near the end wall of the box-trap and is unfolded at an acute angle to the side of the box for support of the end of the unfixed part of the leaf spring on the annular collar of end wall of the pipe.

EFFECT: reduced length and diameter of the valve body, reduction of hydraulic pressure losses at the valve during consumption of liquid environment.
