Abstract: A shut off valve for a hydraulic system is provided. The shut off valve comprises a wall of a hydraulic reservoir, a hydraulic fluid outlet, a valve seat, a valve plate, a valve arm, and a valve control shaft. The hydraulic reservoir is for holding hydraulic fluid. The hydraulic fluid outlet is formed through the wall. The valve seat is provided on an inner surface of the wall encircling the hydraulic fluid outlet. The valve seat has an engagement surface. The valve plate is shaped to engage with the engagement surface of the valve seat. The valve arm is connected between the valve plate and the valve control shaft. The valve control shaft is formed through the wall spaced apart from the hydraulic fluid outlet. The valve plate is configured to rotate about the valve control shaft between a first position in which the valve plate does not cover the valve seat, and a second position in which the valve plate covers the valve seat to shut off the hydraulic fluid outlet. The engagement surface of the valve seat is inclined, relative to a plane of rotation of the valve plate, between the first and second positions such that the valve plate is sealed against the engagement surface when the valve plate is in the second position.

Abstract: An actuator including actuator base, bobbin, and pole piece forming a pocket for a ferromagnetic armature located therein. The actuator including a radial magnet and a solenoid coil constructed and arranged to cause a linear displacement of the armature upon application of a coil drive current from a control circuit. The actuator may include a flexible membrane that partially encloses the armature to form an armature chamber filled with an incompressible fluid. In a valve design, a fluid flow is stopped by driving the membrane against a valve seat. Pressure from the controlled fluid in the conduit is transmitted through the membrane to the fluid within the armature chamber so that the armature does not need to counteract force applied to the membrane by the conduit fluid's pressure. A fluid flow is opened by driving the membrane away from the valve seat.
