  • Patent number: 9022347
    Abstract: A disc for use in a pneumatic valve includes a stiffening insert encased in a flexible body. The stiffening insert acts to protect a central actuation region of the disc against radial compression, which may arise if the disc is used to seal against a bore hole, and against material flow towards the actuation region away from a clamped periphery. The behavior of the disc in a valve assembly is therefore more predictable and reproducible. The flexible body may further be tensioned across the stiffening insert.

  • Publication number: 20080224084
    Abstract: A pressure control valve assembly including a valve body with a valving cavity, a metal insert, a member and ball, a plastic internal ball guide, and a plug. The metal insert, which is received within the valving cavity, includes an exhaust port, a pressure control port, a supply port, and a plug-receiving end. The plastic internal ball guide is included within a portion of the metal insert. The member extends within a portion of the insert and is movable with respect to the exhaust port, the member moving a ball with respect to a supply port. In an embodiment, a plug is received within the plug-receiving end of the insert. A method for making a valve body for a valve assembly is also disclosed.

  • Patent number: 7418781
    Abstract: A peripheral, annular groove is incorporated into a throttle valve connector in one step. A first die and a second die are then inserted into the throttle valve connector and a first plastic material is introduced into a first cylindrical cavity formed thereby in a molten state and hardened, resulting in a plastic insert. The first die and the second die are subsequently removed from the throttle valve connector and a third die and a fourth die are inserted into the throttle valve connector. A second cavity is formed therebetween and filled with a second plastic material, whereby a throttle valve is formed and is fixed during the cooling process by shrinkage on the throttle valve shaft.

  • Publication number: 20080148725
    Abstract: A solenoid operated valve has a pressure transducer sensing valve outlet pressure integrally formed in the valve body, such as by overmolding. Upon connection of the transducer and solenoid to an electronic controller, the controller generates a valve energization signal in response to a desired valve pressure output and the transducer input for providing closed loop control of the valve outlet pressure. An ASIC may also be integrally formed in the valve body, such as by overmolding for providing integrated signal conditioning; and, the optional ASIC, if employed, may also include the circuitry for the electronic controller for providing a “smart” pressure control valve.

  • Patent number: 7367124
    Abstract: This invention relates of the problem, to create a butterfly valve neck without an emergence of a gap between the butterfly valve neck and the butterfly valve. This invention disposes the problem trough a parted butterfly valve neck, with between attached sealing, where the butterfly valve rest on in the closed location. This invention causes, to reduce considerable the leakage air quantity, by the absent of a gap, between the butterfly valve neck and the butterfly valve in the closed location. An inhibition of the butterfly valve in the parted butterfly valve is no more possible. By the inventive sealing of this invention, the motor can operate with a lower idling speed and a smaller emission. Further, an advantage of this invention is the regulation (adjustment) of the dimension of the parted butterfly valve and the sealing, where-by each of the rule curves by starting will achieved from the closed location.

  • Publication number: 20080029157
    Abstract: A shut-off valve assembly includes a one-piece housing having an inlet and an outlet. During manufacture, the housing is formed with an inlet end plate and a fully open end opposite the end plate. A valve door assembly including a flapper door is secured in the housing, and includes a seal between the flapper door and the housing. The open end is then reformed to provide an outlet from the housing. In a fuel system, a cover assembly is releasably secured to the housing.

  • Publication number: 20070113405
    Abstract: A method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve. The method includes providing at least three flat metal plates side by side, each having different magnetic properties directly adjacent to the others. The at least three plates are joined to the directly adjacent bordering edges to form a sheet metal section. The sheet metal section shaped into a sleeve shape. Furthermore, the bordering edges, which are now opposite one another, and run in the longitudinal direction of the sleeve to form a sleeve blank are joined together. The sleeve blank is machined until a desired geometric shape of the housing is achieved. The housing may be suitable in particular for use in fuel injectors in fuel injector systems of internal combustion engines operating by spark ignition of a compressed fuel-air mixture.

  • Publication number: 20060005388
    Abstract: The invention relates to a method and an injector for determining a position of a second part (10) inside a stepped boring (6). This part should assume an exact distance (H) from a first part (2). In order to determine the distance (H) between both parts (2, 10), a collar (3) is firstly introduced into a second boring (6b) of the stepped boring (6) until it rests upon a step (16) of the stepped boring (6). Afterwards, a punch (4), together with a touch probe (5), which is located inside a longitudinal boring (d), is placed upon a lower annular surface (17) of the collar (3) or on an underside (17a) of the first part (2), and the collar (3) is compressed until the predetermined distance (H) is obtained. The distance (H) is measured to a reference measure (x) between a projecting end piece (E) of the touch probe (5) and a reference mark (B) outside of the punch (4). The stamping process is stopped once the reference measure (x) has been obtained.

  • Publication number: 20050120556
    Abstract: A throttle valve and the throttle body are formed substantially simultaneously in the same dies. The melted resin is injected in to a cavity through a pair of valve gates. The valve gates are symmetrically located with respect to the throttle valve shaft. A deformation of the throttle valve can be avoided because a stress concentration on the metal shaft of the throttle valve is reduced in opening the dies.
