  • Patent number: 10877497
    Abstract: Exemplary embodiments are directed to systems and methods used to minimize force variation from a solenoid through an operating stroke. The systems and methods generate a near constant or substantially constant force solenoid assembly which can be used in a force driven device, such as, for example, a pressure regulator for accurately controlling pressure in a pressurized flow system. The systems and methods are based on an initial solenoid characterization and include an application of springs and placement of the solenoid within the system at a gap distance to minimize variation in force in the operating stroke of a commercially available solenoid.

  • Patent number: 10876650
    Abstract: A pressure equalization valve comprises a first pressure cylinder, a second pressure cylinder, an aperture, and a stationary member. The stationary member is located between the first pressure cylinder and the second pressure cylinder. The second pressure cylinder is located within the aperture. A primary piston is located within the first pressure cylinder and a secondary piston is located within the second pressure cylinder. A stem is directly connected to the aperture and the primary piston. The stem includes a fluid passage between the first pressure cylinder and the second pressure cylinder. When a pressurized fluid is introduced into the first pressure cylinder, the pressurized fluid pushes the primary piston and the stem to open the aperture in a linear direction, the pressurized fluid travels to the second cylinder through the fluid passage and pushes against the aperture in the same direction as said first piston further opening the aperture.

  • Patent number: 10859177
    Abstract: An electrically operated gas flow regulating valve causes a needle valve body to move axially by the rotation of an electric motor through a motion conversion mechanism. The mechanism includes: a rotating body rotated by the electric motor; a cylindrical cam body prevented from rotating; a cam pin which is engaged with a spiral cam groove formed in the cam body and which is fixed to the needle valve body. The cam body is divided into two parts of a forward-side half part and backward-side half part with the cam groove serving as a boundary. The backward-side half part is urged by a coil spring in the forward direction such that the cam pin is pinched between the forward-side side edge of cam groove formed in the forward-side half part and the backward-side side edge of cam groove formed in the backward-side half part, thereby restraining the occurrence of hysteresis.
