INTERMITTENT AIR GENERATION DEVICE Russian patent published in 2020 - IPC F15B21/12 F15B11/06 F16K11/07 

FIELD: technological processes.

SUBSTANCE: invention relates to a device for intermittent air generation with possibility of intermittent generation of compressed air. Control valve (14) in intermittent air generation device (10) consists of five-port valve, inlet port (24) connected to compressed air supply source (12), and outlet port (26) connected to air device (18). Supply of pilot air into pilot inlet port (32) provides movement of shutoff element and switching ports (24) and (26) into on state, at which these ports are interconnected, and compressed air is blown from device (18). At the same time discharge of pilot air from port (32) through the exhaust port results in movement of the shutoff element in the opposite direction and switching ports (24) and (26) into an off state, at which communication between these ports is blocked. Switching between on and off states of said ports is intermittent.

EFFECT: invention is aimed at creation of a simple design with low manufacturing cost and possibility of achieving stable operating characteristics.
