A fluid control valve includes a valve member movable into engagement with a seating to prevent the flow of fluid through the valve, and an actuating member which is biased in one direction by a return spring and is moved against the action of the return spring by the armature of the actuator when the winding thereof is energized. The movement of the actuating element is transmitted to the valve member through an under travel spring which yields to allow continued movement of the actuating element when the valve member engages the seating.

Fluid control valve

A pumping apparatus for supplying fuel to an internal combustion engine has a high pressure pump, an adjustable throttle member which is utilized to control the fuel flow from a low pressure to the high pressure pump. An electromagnetic actuator is utilized to adjust the setting of the throttle member and a hydraulic damping device is provided to damp the movement of the throttle member.

Fuel injection pumping apparatus

A fuel injection pumping apparatus for supplying fuel to an engine includes a high pressure pump which receives fuel from a low pressure pump by way of an angularly adjustable throttle member. The throttle member is connected to the armature of an electromagnetic actuator by means of a connecting rod. A transducer is provided which includes a core carried by the connecting rod intermediate the ends thereof and a pair of springs act to oppose the movement of the rod and throttle member by the actuator.

A fuel pumping apparatus comprises a body housing a high pressure fuel pump to which fuel is supplied by an angularly adjustable throttle member from a low pressure pump. The throttle member mounts an arm and a hollow housing is provided which is secured to the body. A support carries an electromagnetic actuator the armature of which is connected at one end to a connecting rod the other end of which is connected to the arm. A transducer is mounted about and movable with the connecting rod. A clamp adjustably clamps the support within the housing and the clamp can be released to enable for a given axial setting of the connecting rod, the output of the apparatus to be adjusted.
