METHOD AND VALVE MECHANISM OF SHORT-TIME HIGH PRESSURE GAS SUPPLY Russian patent published in 2018 - IPC F41B11/72 

FIELD: technological processes.

SUBSTANCE: mechanism comprises a housing, a valve, a stem, wherein the stem is a locking element of the flow section which is intended to move the gas after impact on the outer end of the stem, and a bypass opening. The housing is made in the form of a storage cylinder with an opening for supplying compressed gas from an external gas source. On one side of the housing there is a bush provided with a sealing ring, in which a valve is mounted to form a cavity between the valve and the bush in the closed position of the valve. The bypass opening is located on the other side of the housing. The inner end of the stem and the spring are installed in the valve opening. The flow section is made between the outer end of the stem and the bush with the possibility of gas discharge into the atmosphere, and there are gaps between the valve and the bush wall and between the valve and the inner end of the stem.

EFFECT: valve actuation at small impact energy on the rod, if it is possible to use a valve mechanism to deliver control action to the actuators of pneumatic weapons and weapons simulators, as well as to other various pneumatic mechanisms.
