FIELD: valving. SUBSTANCE: valve comprises hollow cylindric housing with a chamber. The housing is coaxially mounted on a cylindrical body for sliding. The body is provided with inlet and outlet openings in the axial direction which are arranged radially and at an angle to the longitudinal axis. In the middle of the body are two by-passing openings. The axes of the by- passing openings are in the same plane. The inlet opening in the body and one of the by-passing openings are separated from the outlet opening and the other by- passing opening. Sealing rings are set on the body in supports upstream of one by-passing openings and between the other by-passing openings. The housing slides in the sealing rings. EFFECT: enhanced reliability. |
