  • Patent number: 10865891
    Abstract: A control piston (12) is longitudinally displaceable in a housing (10) having two connection points (P, A) for fluid, and cooperates with a metering edge (34) of the housing (10) at a connection point (P). Point (P), in control positions of the control piston (12), supplies the connection point (A) with fluid via a fluid connection. The piston, as a result of occurring flow forces, tends to be drawn in the direction of a closing position that blocks one of these fluid connections. To compensate the flow force, the control piston (12) has, in the region of the control edge (34) of the housing (10), a shape modification (48) of its cylindrical exterior basic form (50), such that a flow contact surface (52) for fluid is created. The contact surface transfers a compensating force that acts against the flow force to the control piston (12) and that seeks to pull the control piston (12) into an opening position opposed to the closing position.

  • Patent number: 10087901
    Abstract: 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.

  • Patent number: 9945328
    Abstract: A low-pressure-loop EGR apparatus of an engine includes an EGR passage to allow part of exhaust gas discharged from a combustion chamber to return as EGR gas to the combustion chamber, and an EGR valve to regulate a flow of EGR gas in the EGR passage. This passage has an inlet connected to an exhaust passage downstream of a turbine and an outlet connected to an intake passage upstream of a compressor. In the intake passage, an intake bypass passage is provided to connect an upstream portion and a downstream part from the compressor. An ABV is provided in the passage. To remove EGR gas remaining in the ABV, one end of a residual gas removal passage is connected to the intake passage downstream of a throttle valve and the other end of the same passage is connected to the ABV.
