VALVE HIGH-PRESSURE DISPENSER Russian patent published in 2017 - IPC F16K11/04 F16K1/36 F15B13/02 

FIELD: machine engineering.

SUBSTANCE: valve hydro-dispenser comprises a housing with an integrated cover and the pusher, as well as medium inlet and outlet channels. A pusher mounted for movement with the control action on its outer part. Between the mentioned channels, at least one valve is located. The valve comprises two parts contact each other - and an annular seat arranged with the possibility of joint movement with spring loaded pusher bolt in the form of a hollow shell.
