ROTOR MULTI-PATH FLOW SWITCH Russian patent published in 1995 - IPC

FIELD: valving. SUBSTANCE: rotor is mounted inside a housing. The rotor is constructed as [-shaped branch pipe having commutation openings. The ends of the branch pipe are coupled with the central supplying passage and shoe. The shoe is mounted for permitting sliding along the base of the housing. The driving axle is mounted on the other base coaxially to the central supplying passage and one of the ends of the branch pipe. The other end of the branch pipe is coaxially mounted in the opening made in the shoe and mounted coaxially to one of the periphery passages. Spherical surfaces are made at the ends of the branch pipe. Concave spherical surfaces are made at the base of the housing opposite to the central supplying passage and in the shoe opposite to the end of the branch pipe coupled with it. The driving axle is coupled with the branch pipe through a carrier. The branch pipe is spring-loaded in the direction of the housing base. EFFECT: enhanced reliability. 1 dwg
