  • Publication number: 20050183770
    Abstract: A switching valve which directs pressurized fluid through alternating pathways in the valve's body is provided, controlled by the cycling of a set of seals between positions, each position providing an alternate fluid pathway. The seals' position during operation is constrained by having the force moving the seals overcome the force of a cam follower on a cam profile to keep the valve from stalling at an equilibrium point.
