A digital inlet valve is the complementary assembly of an armature module, a body module and an actuation module enabling direct control over an air gap between a magnetic armature and a pole piece body.

Digital inlet valve

An inlet valve assembly for a high-pressure fuel pump is disclosed. The inlet valve assembly comprises an inlet valve member moveable between open and closed positions to control the fuel flow from a source of low-pressure fuel to a pumping chamber of the fuel pump, a first biasing spring arranged to apply a first force to the valve member in an opening direction, a second biasing spring arranged to apply a second force to the valve member in a closing direction, and an actuator arrangement operable to remove the first force from the valve member, thereby to allow the valve member to move into its closed position.

Valve assembly

A plug assembly is provided for a high-pressure valve of the type with a tubular body extending along a longitudinal axis and in which, under the action of a piloted actuator, a needle moves longitudinally between a closed position and an open position. The plug assembly includes a plug having a flat part able to be fixed onto the body transversally to the longitudinal axis, and a spring intended to apply to the needle a force biasing it axially towards the closed position. The spring is fixed to the plug forming with it an integrated assembly.
