FIELD: process engineering.
SUBSTANCE: proposed device comprises fluid chamber, tube to transfer fluid inside said chamber into fluid sprayer first and second elements covering said tube on both sides, and cam to register position of said first element with respect to second element. Said tube is furnished with flexible elastically deformable oblate-shaped part. Cam in first angular position arranges the first element to make clearance for portion of fluid to flow between first and second element. Cam in second position arranges said first element to make flexible part compressed by first and second elements to prohibit ingress of fluid flow.
EFFECT: decreased probability of fluid leaks from sprayer.
