  • Patent number: 8528879
    Abstract: The invention relates to a method and a device for producing a high-pressure-tight connection between a pole core and a valve sleeve of a solenoid valve and to an associated valve cartridge for a solenoid valve. According to the invention, the pole core is placed in a two-part compression mold, which comprises a middle die and an outer die, in such a way that a joining gap is produced between an inner bore of the outer die and the placed-in pole core. Subsequently, the pole core is placed against the valve sleeve and the valve sleeve is inserted into the joining gap. Then, the middle die and the outer die are pressed simultaneously with the pole core such that the valve sleeve passes into the joining gap. When a pressed diameter of the pole core is reached, the valve sleeve expands and is shaped in the joining gap between a first shaping edge and a second shaping edge and is joined onto the pole core. The diameter of the inner bore tapers between the first shaping edge and the second shaping edge.

    Abstract: An automatic transmission control unit determines whether or not a constantly open failure, in which a switch valve cannot switch a pressure regulating valve and a second hydraulic chamber to a non-communicative state, has occurred on the basis of a parameter (an inertia phase time, for example) representing a dynamic characteristic during a shift from a first gear position to a second gear position. The determination of the constantly open failure is begun after initial variation in the parameter representing the dynamic characteristic during the shift has been eliminated through learning control in which the dynamic characteristic during the shift is caused to approach a target dynamic characteristic.

  • Patent number: 7017885
    Abstract: In the region in which a coil and a connector are provided, the leakage of a fluid to which coil and connector is prevented by a seal member, a passage extending from the seal member to a position in the vicinity of a terminal of the connector is formed. At the time of completion of the production of a solenoid valve assembly, an air-tightness test on the seal member can be conducted directly through the passage, so that the detection of damage to the seal member, the detection of bite into the seal member, the detection of a defect of the seal member and so on can be carried out at the time of completion of the production of the mentioned assembly. Namely, the detection of the sealability of the seal member is rendered possible.

  • Patent number: 6955337
    Abstract: A pneumatic module includes an actuator assembly and a manifold. The actuator assembly includes a main body having a bore, an armature, overmolded primary and secondary plates, a coil and a frame. The manifold includes a valve seat, a control port and a supply port. When the actuator is in a de-energized state, the armature is forced against the valve seat by a spring, sealing off the supply port from the control port. When the actuator is in an energized state, current flows through the coil, thereby generating a magnetic field. The magnetic field forces the armature to move toward the primary plate, causing the valve seat becomes unsealed. Once the valve seat is unsealed, fluid flow is permitted between the supply port and the control port. The one end of the armature has an endcap to minimize mechanical noise generated by movement of the armature against the spring. The frame surrounding the actuator assembly has flanges extending from both ends.

  • Patent number: 6834667
    Abstract: In a fuel injection valve, an adjustment pipe made of stainless steel and for adjusting a compression amount of a spring biasing a valve member is press-fitted into a cylindrical housing made of stainless steel, and a fuel injection amount is adjusted by adjusting a spring force of the spring in accordance with a press-fitted amount of the adjustment pipe. The adjustment pipe is immersed in an oxalic acid solution so that an oxalate film is formed thereon before being press-fitted into the cylindrical housing. Therefore, the oxalate film prevents a direct press-contact between an outer peripheral surface of the adjustment pipe and an inner peripheral surface of the cylindrical housing.
