A high pressure valve includes a body on which is fixed an electromagnet, the shell of which has a radial discal part provided with a central hole connecting an internal opposite surface to an external surface. The body is provided with a cylindrical external centring surface and with a radial support surface. The shell is arranged on the body around the centring surface, the external discal surface being in surface contact against the support surface of the body. The coil of the electromagnet is arranged in the tubular space between the body and the shell itself closed by a closure ring. The liquid-tightness between the body and the shell is ensured by a gasket compressed by a wedging washer against the centring surface and against the internal discal surface. The shell is then immobilized on the body by the wedging washer.

High pressure valve

An arrangement of a high-pressure valve at the end of a common rail of a fuel injection system, a high-pressure channel of the rail opening out at one extremity of the rail, includes a throttle stopper arranged at the extremity of the rail. An output orifice restricts a section of the high-pressure channel and a valve seat is positioned in the throttle stopper. The output channel is fully formed inside the valve body.

Integrated arrangement of a high-pressure valve and an injection rail

A nozzle able to be arranged in a diesel injection system of the internal combustion engine of a vehicle comprises a fixed member provided with a nozzle seat at the center of which there opens a discharge orifice, the fixed member comprising a cylindrical tubular part defining an inner guide cylinder extending axially from an open first end as far as the seat that forms the closed end of the guide cylinder, and a shut-off member arranged and guided in the guide cylinder, the shut-off member being able to move between a closed state (EF) when the shut-off member is in abutment against the seat and an open state (EO) when the shut-off member opens the discharge orifice.

An electro-valve for discharging a common rail while maintaining a minimum pressure, comprising an electro-magnetic coil inside which is arranged a movable plunger, controlling the displacements of a movable axis engaging a ball valve, said movable plunger being urged in the closing position of the ball valve by a spring housed inside a bearing cap, wherein a bottom wall of the bearing cap surrounds an external surface of the movable plunger, wherein a clearance between the external surface of the plunger and an internal wall of the bearing cap is filled with a film of fuel, the opening movement of the plunger causing the fuel to flow from a room situated on top of the plunger to a bore in which the axis is arranged, wherein a sleeve of a controlled thickness is arranged around the plunger within the clearance to set the thickness of said film of fuel.

Electro-valve for discharging common rail

A vehicle roll control system, comprising a front torsion bar(), attached to the front hydraulic actuator () and a rear torsion bar () attached to the rear hydraulic actuator (). A pressure control valve () is fluidly connected between a pressure source () and a reservoir (). A directional valve () is fluidly connected between the pressure control valve () and the hydraulic actuators (). A pressure relief valve () fluidly connects the directional valve to the pressure source () or the reservoir () and is actuated to create pressure differential between first fluid chambers () of the hydraulic actuators ()and/or to create pressure differential between second fluid chambers () of the hydraulic actuators ().

Vehicle roll control system

A vehicle roll control system comprises a torsion bar and a first arm extending-substantially perpendicular to the torsion bar. The first arm is fixed to the torsion bar at one end and connectable to one of the axles at the other end. A hydraulic actuator is attached to the torsion bar; and a control connected to the hydraulic actuator controls the operation thereof on detection of a predetermined vehicle condition. The hydraulic actuator comprises a housing, a piston making a sealing sliding fit inside the housing to define a first fluid chamber and a second fluid chamber, and a piston rod connected to the piston and extending through the second fluid chamber and out of the housing. The control acts on detection of the predetermined vehicle condition alternatively (1) to apply substantially the same fluid pressure to the first and second fluid chambers when the piston tends to move in a first direction to extend the hydraulic actuator, or (2) to apply a fluid pressure to the second fluid chamber above the fluid pressure in the first fluid chamber when the piston tends to move in a second direction to compress the hydraulic actuator. The control comprises a first directional valve and a second directional valve, each directional valve being capable of moving between first and second positions either to tend to move the piston in the first direction or to tend to move the piston in the second direction.
