  • Publication number: 20230204129
    Abstract: An overrun-air recirculation valve includes a flow housing having a flow channel, a valve seat, an actuator, an actuating member movable via the actuator, and a control body fastened to the actuating member. The control body has a lateral outer surface having a bearing edge which is placeable onto and liftable off of the valve seat, a flow-on surface arranged on an axial side facing away from the actuating member, and a wall extending radially inwardly from the lateral outer surface. The flow-on surface has a flow-off edge offset axially to the bearing edge so that a first vector extending radially outwardly from the flow-off edge to a nearest point of the bearing edge to a plane spanned by the bearing edge encloses an angle of <15°, and the wall is offset axially to the bearing edge and to the flow-off edge in a direction of the actuating member.

  • Patent number: 9140621
    Abstract: An arrangement for the direct contacting of contact mechanism has a first contact mechanism arranged on a contact carrier and a second contact mechanism. The second contact mechanism acts with a predetermined contact force on the first contact mechanism. The contact carrier includes a plastic injection premolding of galvanizable plastic and a nongalvanizable plastic. The galvanizable plastic has a predetermined resilient behavior and the first contact mechanism is formed by a metal layer having predetermined dimensions. The first contact mechanism can be applied onto the galvanizable plastic in a galvanic process. The resilient behavior of the galvanizable plastic and the dimensions of the metal layer form, under the predetermined contact force, a microdepression configured to guide the second contact mechanism in the first contact mechanism. A corresponding connection device for a pressure measurement cell includes such a direct contacting arrangement.

  • Patent number: 6681143
    Abstract: A method is provided for matching dimensions of a spool to a control valve body of a fuel injector. The method includes the steps of measuring land locations and an overall length of a first component of the fuel injector and measuring land locations of a second component of the fuel injector relative to at least each other. The method also includes calculating a grinding amount to be removed from the second component based on the following criteria (i) the measured land locations and the overall length of the first component and (ii) the measured land locations of the second component relative to each other.

  • Patent number: 6631853
    Abstract: An oil activated fuel injector control valve which substantially eliminates captured air within working fluid of the fuel injector. This eliminates shot by shot variations in the fuel injector as well as increasing the efficiency of the fuel injector. The fuel injector includes a control valve body which has vent holes which prevent air from mixing with the working fluid. In this manner, the working fluid does not have to compress and/or dissolve the air in the working ports prior to acting on the piston and plunger mechanism in an intensifier body of the fuel injector.
