ABSTRACT:
A slide valve comprising a housing in which a slide is movably guided between two oppositely facing, flat contact surfaces. Communication between fluid passages in the housing is accomplished by hollow formed passage means on the slide. Seal rings carried in grooves in the slide maintain sealing contact between the slide and the contact surfaces of the housing and seal off the fluid passages relative to each other. Each seal ring consists of a band-shaped contact member and a resilient support member. The support member is arranged to bias the contact member against the contact surface by a force uniformly distributed over the entire length of the contact member.
