Publication number: 20200132206Abstract: A cooling fluid valve having an actuator portion extending outwardly beyond an outer surface of an actuator housing. The cooling fluid valve actuator portion includes a plug force fit into an orifice in a valve housing. The plug blocks flow of cooling fluid from a cooling fluid inlet to a cooling fluid outlet. The cooling fluid outlet is connected to communicate cooling fluid to the component. The plug is formed of a material having a first coefficient of thermal expansion. A portion of the valve housing includes the orifice receiving the plug being formed of a material having a second coefficient of thermal expansion with the second coefficient of thermal expansion being higher than the first coefficient of thermal expansion, such that when the actuator portion of the valve is exposed to heat, the force fit may be eliminated as the valve housing expands at greater rate than the plug.Type: ApplicationFiled: October 26, 2018Publication date: April 30, 2020Inventors: Bruce D.

Publication number: 20200132207Abstract: A control mechanism locks open a spring-loaded valve and automatically releases the spring-loaded valve to close upon a predetermined lesser weight load being applied. The spring-loaded valve includes a flow valve, a valve lever that pivots between open and closed positions, and a valve spring that biases the valve lever to the closed position. The control mechanism includes a pivotal release lever having an engagement arm and an opposite load arm, and a release spring that biases the release lever from a blocking position with the engagement arm retaining the valve lever in its open position to a release position with the valve lever free to pivot past the engagement arm and to the closed position under the valve spring force. The load arm includes an additive-container support for a load of an additive fluid to be mixed with a carrier fluid whose flow is controlled by the valve.Type: ApplicationFiled: October 30, 2019Publication date: April 30, 2020Applicant: PRODEW, INC.Inventors: Itamar KLEINBERGER, Shakeel MERCHANT, Paul WILHELM, Kendall C.

Publication number: 20200132208Abstract: A valve is provided and includes a valve body defining a pathway, a diaphragm and a wire. The diaphragm is configured to assume first or second conditions in which the diaphragm blocks or permits fluid flow through the pathway, respectively. The diaphragm is biased toward assumption of the first condition. The wire is coupled to the diaphragm. The wire has an uncontracted length in an unheated state whereby the wire permits assumption of the first condition by the diaphragm due to the bias and a contracted length in a heated state whereby the wire pulls the diaphragm toward assumption of the second condition in opposition to the bias.Type: ApplicationFiled: March 13, 2019Publication date: April 30, 2020Inventor: Vinay Kumar Srinivasa Murthy

Publication number: 20200132209Abstract: An electric motor-driven, rolling element screw linear actuator is presented which work in cooperation with an hydraulic actuator and share several components. This is achieved through the integration of a screw-driven integrated nut piston assembly. Combining the use of an electric screw driven actuator can also reduce the need for a redundant hydraulic system, resulting in the elimination of 50% of connections, valves, piping, pumps, filters etc., while still being 100% redundant. An additional advantage is that the two drive systems are technologically independent, and therefore will not both fail because of an identical component flaw or failure point. The systems may also be used at the same time if conditions require force in excess of that generated by the hydraulic actuator alone.Type: ApplicationFiled: October 26, 2018Publication date: April 30, 2020Inventor: D.

Publication number: 20200132210Abstract: A solenoid valve includes: a valve body with a valve seat therein; a sealing assembly provided on the valve seat; and a plunger to be driven by a solenoid to make the sealing assembly open or close the valve seat. The solenoid valve is characterized in that: a casing is coupled to the valve body and has an outer bottom portion protrudingly provided with a guide post; a flow channel is formed in the guide post; the sealing assembly includes a rigid disk, a flexible diaphragm, whose bottom side faces an orifice of the valve seat, and a central opening, in which the guide post is partially fitted; and the plunger has a bottom portion facing the inlet of the flow channel. With the guide post being stationary and linking the plunger and the sealing assembly, the solenoid valve features reduced power consumption and a low chance of solenoid failure.Type: ApplicationFiled: December 10, 2018Publication date: April 30, 2020Inventor: SUNG AN LAI

Publication number: 20200132211Abstract: An electromagnetic valve as a fluid device is provided with a valve seat and a valve body midway of a flow path where a liquid flows, and closes the valve with the valve body pressed onto the valve seat and opens the valve by causing a gap between the valve seat and the valve body. The electromagnetic valve includes, as electrodes for measuring a degree of electrical conductivity between a liquid on an upstream side and a liquid on a downstream side of the valve seat and the valve body in the flow path, a first electrode electrically conductive to the liquid on the upstream side and a second electrode electrically conductive to the liquid on the downstream side. By using the first and second electrodes, detection of liquid leakage can be easily performed.Type: ApplicationFiled: November 6, 2018Publication date: April 30, 2020Applicant: TAKASAGO ELECTRIC, INC.Inventors: Hiroyuki SUGIURA, Yutaka HAYASHI, Ken NAITO, Masaaki INOUE

Publication number: 20200132213Abstract: Actuators having electroactive valves are described herein. The actuators can move from a first position to a second position and lock in the second position using an electroactive valve. The device can include an actuator having a fluid-impermeable membrane. The fluid-impermeable membrane can define a compartment, the compartment having a central region, an edge region extending from and fluidly connected with the central region, an electroactive valve between the central region and the edge region, and a dielectric fluid. When actuated, the actuators can force fluid through the electroactive valves and into the edge region. Once in the edge region, the electroactive valves can prevent return flow until receiving an actuation signal.Type: ApplicationFiled: October 25, 2018Publication date: April 30, 2020Inventors: Umesh N.

Publication number: 20200132216Abstract: Provided is a flow rate control apparatus capable of being used continuously when the apparatus is used in equipment that operates continuously, and a flow rate control method for the flow rate control apparatus. A flow rate of a fluid is controlled via any one of control valves disposed in branch passages, respectively. When replacement of the one control valve is determined to be necessary on the basis of a signal outputted from a monitoring portion of the one control valve, the one control valve performing flow rate control is closed, and another control valve disposed in another one of the branch passages, is opened, to perform flow rate control with a flow rate equivalent to that before the replacement. Furthermore, on-off valves disposed at upstream and downstream sides of the closed control valve are closed.Type: ApplicationFiled: June 21, 2018Publication date: April 30, 2020Applicant: Fujikin IncorporatedInventors: Takashi FUNAKOSHI, Yoshinori SHIMOMURA, Tsuyoshi TANIKAWA, Tadayuki YAKUSHIJIN
