INLET VALVE OF PISTON PNEUMATIC MACHINE Russian patent published in 2024 - IPC F16K15/02 F16K15/06 F01B25/10 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to piston-type pneumatic machines. Inlet valve of the piston pneumatic machine includes a cylindrical hollow housing having on its outer surface a thread designed so that to enable interaction with a mating thread on the head of the cylinder block of the device. Thread on the outer surface of the cylindrical hollow housing interacts with the lock nut to adjust the height of the fixation of the inlet valve. In the lower part of the cylindrical hollow housing there is an outlet hole with a surface bevelled under the cone, which forms a seat. Valve head comprises pusher to interact with piston during device operation, working part made with conical surface interacting with seat during operation, and support part containing recess for spring installation. In the upper part of the cylindrical hollow housing there is a bushing containing on its outer surface a thread interacting with the thread on the inner surface of the cylindrical hollow housing. Wherein said bushing comprises working medium inlet and recess for spring mating part to be fitted therein.

EFFECT: invention is aimed at improvement of reliability of device operation, improvement of repairability, improvement of synchronization of inlet valve with piston system with simplicity of design.
