se Hard seal plug valve By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT The invention provides a hard seal plug valve, comprising a valve body, wherein a tapered plug is arranged in the valve body, a bonnet is arranged at an upper part of the valve body, a drive valve rod penetrates the bonnet, an elastic hold-down mechanism is sheathed on the drive valve rod and arranged on a plug bearing seat, the plug bearing seat is connected with the tapered plug, and the plug bearing seat is held down when the elastic hold-down mechanism extends; and the hard seal plug valve characterized in that a telescopic mechanism is sheathed on the drive valve rod, the plug bearing seat is pushed upward when the telescopic mechanism extends, a valve rod bearing seat is arranged at the bottom of the drive valve rod, ends of the valve rod bearing seat pass through a planetary reduction mechanism, and the tapered plug is connected with the planetary reduction mechanism and rotates with the drive valve rod by the planetary reduction mechanism. In the invention, the tapered plug can reliably float and rotate under any circumstances. The drive torque of the plug valve is at least 7 times less than that of a general plug valve, therefore, when a motor is used, a general valve requires 2 minutes from opening to closing, and the valve of the invention only requires 3.8 seconds.

se Fuel system valve assembly By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT A fuel system valve assembly may include a housing, a spring, and a body. The housing may have a fuel passage defined in part or more by a fuel passage wall. The fuel passage wall may have a seat and a cylindrical section. The cylindrical section may have a constant diameter and may be located downstream of the seat. In use, the body may reciprocate linearly in the housing between an open position and a closed position. The body may be biased to the closed position by the spring. The body may abut the seat when the body is in the closed position. Full Article
se Steplessly adjustable hydraulic insert valve By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT A steplessly adjustable hydraulic insert valve has a housing defining a radial direction and an end side in an installation direction. An inflow connector on the end side is connectable to a pressure medium source. First and second working connectors and a return connector are arranged in the radial direction. The return connector is connectable to a pressure medium tank. The housing has an axial bore and an actuator guided movably therein. The actuator can be held in an axial center position by at least one spring and is adjustable steplessly axially out of the center position by controllable actuation. At least one of the working connectors is fluidically connectable to the return connector by axial adjustment of the actuator. The actuator has a radial widened portion with first and second control edges for steplessly opening and/or closing first and second radial openings, respectively, of the return connector.

se Power-efficient actuator assemblies and methods of manufacture By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT Power-efficient actuator apparatus and methods. In one exemplary embodiment, the actuator assembly utilizes a shape memory alloy (SMA) filament driven by an electronic power source to induce movement in the underlying assembly to actuate a load (e.g., water valve). In addition, a circuit board is included which allows the actuator assembly to be readily incorporated or retrofit into a wide range of systems such that the signal characteristics of the supply line can, among other applications, be conditioned in order to protect the SMA filament. Furthermore, the circuit board can also readily be adapted for use with “green” power sources such as photovoltaic systems and the like. Methods for manufacturing and utilizing the aforementioned actuator assembly are also disclosed. Full Article
se Filler assembly for a valve By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT A filler assembly is mounted in an axial hole of a cap of a valve. The filler assembly includes at least one first filler and at least one second filler stacked in a longitudinal direction. A valve rod received in the axial hole extends through the at least one first filler and the at least one second filler. At least one of two mutually abutting faces respectively of the at least one first filler and the at least one second filler is at a non-parallel angle to a radial direction perpendicular to the longitudinal direction. If one of the at least one first filler and the at least one second filler is subjected to a pressing force in the longitudinal direction, at least one of the at least one first filler and the at least one second filler is moved in the radial direction to press against the valve rod.

se Low torque, high flow and tight sealing tube butterfly valve By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT A butterfly valve including a valve body having a passage, a valve shaft assembly, a valve plate, and a tube that is friction fit inside the passage is provided. The valve shaft assembly includes a first shaft portion and a second shaft portion. The first and second shaft portions are in opposing spaced relation with the valve plate disposed therebetween. The valve plate has a flange such that when the butterfly valve is in the closed position a seal is formed with the tube, which is disposed within the fluid flow passage. The valve plate has lip extending from a portion of the valve plate that is radially outward from the circumference of the tube. The lip acts to reduce flow induced torque experienced while the valve plate is actuated from the closed to the open position. Full Article
