DISTRIBUTOR WITH ROTATING U-SHAPED CONNECTING CHANNEL Russian patent published in 2013 - IPC F16K11/74 

FIELD: machine building.

SUBSTANCE: distributor (5) includes at least two outlet channels and one supply channel and housing of distributor (12,17,18), which is located so that it can be rotated about axis with supply end (12') placed along the axis, and outlet end (12") placed along the radius at some distance from it. The latter is selectively brought into interaction as to fluid medium with the corresponding outlet channels (10, 16) by turning the distributor housing. Liquid supplying channel (11) passes along central axis (13) and along outlet channels (10, 16). The distributor housing includes U-shaped connection channel (12) and can be placed together with the end of supply channel (12') with possibility of being turned as a continued part of supply channel (11) in connection as to fluid medium with the corresponding outlet channels (10, 16). U-shaped connection channel (12) has ventilation duct (32) in close proximity to upper side. Channel (32) passes through channel (12) wall forming the perimeter in the direction of the flow movement to U-shaped channel (12).

EFFECT: improving actuation reliability of the device due to its ventilation.
