  • Control valve for a hydraulic switch clutch
    Patent number: 5123509
    Abstract: Hydraulic pressure representing engine throttle position is applied to a valve spool having two control surfaces. In opposition to the force of a control spring, a pressure line, which opens to the valve chamber between the two control surfaces, carries regulated line pressure through a flow orifice in a first connecting line and through an aperture stop in a second connecting line. The flow orifice of the first connecting line is arranged in parallel with an aperture of the second connecting line, both the first and second connecting lines being connected directly to the valve chamber.
