  • Patent number: 10332707
    Abstract: An actuator driven by combustion of powder satisfactorily transmits energy for driving an output part to the output part. An output piston part has a specific end face that receives driving energy. A sealing member confines the combustion products in a first space separated by the sealing member. The sealing member has a fixed end portion and a contact portion that is in contact with the specific end face. In a state before the combustion of powder in an igniter, the contact portion is located at an initial position. With the combustion of powder in the igniter, the contact portion shifts to an operative position with the sliding motion of the output piston part while being in contact with the specific end portion.

  • Patent number: 9828832
    Abstract: A tool string carrying an external tool, such as a liner hanger, on a release mechanism is lowered into the wellbore. Interlocking lugs and J-slot profile, defined between the exterior surface of the mandrel and interior surface of the release mechanism, allow relative movement of release mechanism and mandrel without releasing the release mechanism. The relative movement allows mechanical operation of a valve or other tool positioned below the release mechanism. Weight-down and rotation of the tool string and mandrel actuates the lower valve assembly by turning a sleeve into alignment with cooperating members of the mandrel. The sleeve, no longer constrained, moves longitudinally in response to a biasing mechanism. Movement of the sleeve allows closure of the valve. After actuation of the valve tool, further weight-down releases the release mechanism from the carried tool.

    Abstract: A dehumidifier for a compressor, including: a plurality of dehumidifying members that absorb moisture; and a flow passage controlling valve module that enables a low-temperature vapor refrigerant to alternately flow into the plurality of dehumidifying members and enables the low-temperature refrigerant to flow into a compressor in a state where moisture contained in the low-temperature refrigerant is absorbed and is removed, enables a high-temperature vapor refrigerant ejected from the compressor to alternately flow into the dehumidifying members and regenerates the dehumidifying members. Thus, since a liquid-state absorbent contained in a refrigerant flowing into the compressor is removed by the dehumidifier, damage caused by liquid compression and corrosion of the compressor can be reduced. In addition, the structure of the dehumidifier is simple, and an additional external heating source is not required.

  • Patent number: 9004094
    Abstract: The present invention concerns a valve (1), a valve closing body (14) and use of a valve (1) and a valve closing body (14) of the type used for injecting dry powder which is mixed with liquid, and where the dry powder is supplied under the liquid surface in a mixing vessel (11) in which a vacuum is typically maintained. The novel feature of a powder valve (1) according to the invention is that a closing body (14) of the valve in the closed position extends through the valve seat (13) of the valve and into the wet environment. It is hereby achieved that when the valve (1) is opened, powder or dust from powder is not deposited on the valve closing body (14). This is in spite of the valve closing body (14) being wet, due to contact with the liquid to which the powder is added. Due to its elongated shape, the valve closing body (14), which in the withdrawn position opens for inflow of powder, has the property that the inflowing powder dries the valve closing body (14) at first and keeps it dry subsequently.

  • Publication number: 20150096619
    Abstract: An apparatus has a pilot-operated spool valve connecting first and second work passages selectively to a supply conduit and a tank conduit. A first check valve normally allows fluid flow only in one direction from the first work passage to a first workport and when pilot-operated allows bidirectional fluid flow. A second check valve normally allows fluid flow only from the second work passage to a second workport and when pilot-operated allows bidirectional fluid flow. A first pilot valve selectively applies pressure to one end of the spool and to pilot operate the first check valve. A second pilot valve selectively applies pressure to another end of the spool and to pilot operate the second check valve. When fluid drains from a workport to the tank conduit, the associated check valve operates to maintain a predefined pressure in the first or second work passage through which that fluid flows.

  • Publication number: 20140261717
    Abstract: A valve system is provided that includes an electromechanical solenoid, a gas valve including a magnetic flapper, a power source in electrical communication with the electromechanical solenoid, and a controller. The controller is configured to control the power source to supply an intermediate voltage that causes the electromechanical solenoid to move to a neutral position between a default position and a fully-actuated position. In so doing, the magnetic flapper is maintained in a neutral position between two gas ports and a flow of gas between the ports can be used to clean foreign particles from the magnetic flapper. The controller can also provide a varying voltage to the electromechanical solenoid while in the neutral position to cause vibration of the magnetic flapper and further assist in removing foreign particles. A closed loop system including a feedback circuit can be used for adjusting the voltage applied to the solenoid based on pressure sensed.

    Abstract: A method and a fluid tap device for retaining the temperature of a liquid, in a liquid distribution system having at least one liquid conduit extending from a liquid source to a liquid tap. After completion of a tapping operation and replacing the liquid with gas in the conduit, the refilling of liquid in the conduit is performed in three steps: a first step, initiated by activating the tap thereby causing a change of a physical variable which propagates backwards along the conduit and initiates a second step, the second step involving refilling the conduit with liquid from the source, while permitting remaining gas to escape via a gas passage separate from a liquid passage in the tap, and a third step, initiated when the liquid reaches the tap, involving opening the passage and permitting the liquid to flow out via the passage and through the tap.
