FIELD: mechanical engineering. ^ SUBSTANCE: device has body with input, output and draining channels, cover, spring-loaded membrane, placed between body and cover, saddle, nozzle of which is covered by spring-loaded valve, pusher, passing through saddle nozzle and stopping against valve in lower portion, and against membrane in upper portion. Saddle in lower portion along outer diameter has ring-shaped recess, forming a ring-shaped hollow together with ring-shaped recess in body, which hollow is connected to output channel. Saddle nozzle is connected by radial channels to ring-shaped hollow. One of radial channels is connected by vertical channel to sub-membrane hollow, which is connected to draining channel. ^ EFFECT: broader functional capabilities. ^ 1 dwg |
