  • Patent number: 9385564
    Abstract: The invention intends to improve a stator which is detachably installed to an outer peripheral portion of a can accommodating a rotor. The stator is integrally formed with a resin mold by arranging a stator assembly (110) within metal molds (300, 310) and injecting a molten resin (P1) from a gate (G1) at one position. An annular plate (160) is mounted to an upper portion of the stator assembly (110) so as to prevent the molten resin from intruding into magnetic pole teeth (120a, 122a), and prevent a weld line from being generated in an outer peripheral surface of the resin mold.

  • Patent number: 9091339
    Abstract: A compliant cam system includes a cam having a cam body rotatable with respect to a cam rotational axis. The cam body has a cam body center spaced from the cam rotational axis. At least a portion of the cam is an elastically compressible material. A follower having at least one follower surface is in contact with the compressible material portion of the cam. A cam non-deflected condition is defined when an elastically compressible material portion outer surface is in contact with the cam follower surface prior to deflection of the elastically compressible material portion. The cam when thereafter rotated with respect to the cam rotational axis moves the cam body center toward the follower. The elastically compressible material portion deflects, defining a deflected condition, creating a biasing force acting toward the follower, and releasably frictionally engaging the elastically compressible material portion with the follower.

  • Publication number: 20150129071
    Abstract: A rotary shear valve having three-point stator seating is provided. Three contact points are predetermined between a bottom of the stator and a valve body rim and three clamping pads may also be predetermined. The three clamping pads and the three points of contact between stator and the valve body rim are corresponding and aligned when the rotary shear valve is assembled so that the clamping or compression forces on both sides of the stator directly oppose one another, thereby effectively canceling each other. In one embodiment, the stator includes three contact points on the bottom surface proximate the periphery of the stator to contact the valve rim and a gasket includes three clamping pads proximate the periphery of the gasket web to apply a compression force on the top surface of the stator above the three contact points.

  • Patent number: 9024591
    Abstract: A most recent electrostatic capacitance value for a backup capacitor is measured periodically. Each time the most recent electrostatic capacitance value is measured, a charging voltage (a required charging voltage) that is required in order to cause a return operation of a valve from the setting opening at that time to an emergency opening/closing position (for example, the fully closed position) is calculated based on the electrostatic capacitance value that has been measured, and the terminal voltage of the backup capacitor is adjusted so as to become equal to the calculated required charging voltage.

  • Patent number: 9016662
    Abstract: A powered valve actuator assembly converts a manually operated valve without removal of the valve handle for automated valve operation in response to detection of a preselected condition. The design incorporates a motor, motor control circuit, drive shaft, valve handle engaging member and anti-rotation member. The motor is supported by its drive shaft, which is mounted on the valve handle via an adaptor. The motor, when operated, applies rotational torque to the drive shaft, and is secured from counter rotation about the drive shaft by the anti-rotation member, which extends between the motor and a fixed reference point with respect to the valve body such as the conduit or an extension thereof. The control circuit may incorporate a monitoring sub-circuit and power regulator, which operates at reduced power levels depending on the sensed state of the sensor or sensors.

  • Publication number: 20150108381
    Abstract: An electromagnetic valve apparatus with nonlinear springs for variable valve timing in an internal combustion engine. The apparatus includes a valve, floating spring assembly, translational cam, and motor. The cam and spring serve to minimize lash and valve stem bending forces. During opening and closing of the valve, spring potential energy is converted into valve kinetic energy and then back into potential energy at the end of the motion. The potential energy is then available for the next opening/closing event. The motor initiates motion, replaces friction and vibration losses, and terminates motion. However, the motor supplies minimal energy as the valve opens and closes, and vice-versa, naturally due to combined effects of system inertia and the nonlinear spring. In addition to valve control, the apparatus may be applied to fuel injectors, or any reciprocating linear or rotary mechanism where electronic control is used.

  • Publication number: 20150102039
    Abstract: A vapor purge system having a tank isolation valve and a canister vent valve, where each valve includes a latching mechanism for maintaining the valves in an open position. A diagnostic test is performed on the purge system to prove that each of the valves are functioning correctly. Using latching valves in these applications reduces electricity draw from the battery and reduces electrical interference with integrated pressure sensors. The fuel tank is sealed by the tank isolation valve between the fuel tank and a vapor storage canister, and the canister vent valve provides sealing between the canister and the atmosphere, and controls venting of the canister. The tank isolation valve reduces power consumption from the battery, while the valve is being held in either an open position or a closed position by the latching mechanism, and uses only a single pulse of voltage to change the state of the valve.

  • Patent number: 8978687
    Abstract: An actuating device or displacing a control device, such as a valve, gate valve or other control mechanism, in particular for use in oil or gas production systems, comprises a motor-gear unit (21) and a thread drive (22) which is operable by said motor-gear unit (21) and which comprises at least a threaded spindle (23) and a screw nut (24). The threaded spindle (23) is displaceable in an essentially axial direction so as to displace the control device (2) between a use position (7) and a non-use position (8, 9, 19, 20). To ensure a safe displacement into the non-use position in a simple way and independently of the pressure conditions prevailing between conveying medium and inner medium, the threaded spindle (23) is substantially axially displaceable beyond the use position (7) into a second non-use position (9). The invention also refers to a corresponding method for displacing the actuating device.

  • Publication number: 20150069279
    Abstract: The invention relates to an axial valve comprising an actuator (15) and a center tube (19). The actuator comprises a stationary element (16) and a closing element (17), and the center tube (19) is placed axially in relation to an axial extension of the stationary element (16). The center tube (19) is in a fixed position relative to the stationary element (16). Fluid, such as refrigerant, is intended for flowing through the valve and through the center tube. The center tube (19) comprises orifices (22) for fluid passage. The closing element (17) is placed axially to an axial extension of the center tube (19) and is movable axially along the center tube between a first position, where the closing element closes the orifices (22) of the center tube, thereby not allowing fluid to pass the orifices, and a second position, where the orifices (22) are open, thereby allowing fluid to pass the orifices.
