  • Patent number: 10876729
    Abstract: An apparatus that regulates the size and intensity of a torch flame by controlling the release of oxygen and a fuel, such as propane. The apparatus releases oxygen and fuel by pivoting a flame control plate that opens and closes mini ball valves using a mini ball connecting bracket. The further forward the plate is pivoted, the more open the valves become increasing the size and intensity of the torch flame. Slotted holes at different angles on the mini ball valve connecting bracket cause the apparatus to release oxygen first resulting in a quiet flame ignition and to release oxygen last to blow out the last flow of fuel, resulting in a safe operation.

    Abstract: A valve subassembly includes a main spool having a continuously adjustable main orifice and a control spool having adjustable first and second orifices. The control spool has first and second end positions and is acted upon by a first spring toward the first end position. A fluid flow path starts from a pump and runs to an actuator via the first orifice, first control point, second orifice, second control point, main orifice, and third control point. Pressure at the first control point acts on the control spool toward the second end position and pressure at the third control point acts toward the first end position. The second orifice is closed between the first end position and an intermediate position, and opens from the intermediate position to the second end position.

  • Patent number: 9175456
    Abstract: A boom control valve and a pulsation absorption control valve are provided in the halfway point of a center bypass line. The pulsation absorption control valve is arranged in a position downstream of the boom control valve. The pulsation absorption control valve is switched to a blockade position and a communication position by a pilot pressure from a remote control valve. The pulsation absorption control valve is constituted such that one main line out of a pair of main lines is communicated with or blocked off from an accumulator via one communication line and the other main line is communicated with or blocked off from the side of a tank via the other communication line. The accumulator is operated as a dynamic damper at the traveling of a vehicle. This arrangement enables the construction of the communication line to be simplified, thus improving operability at assembling.

  • Patent number: 9115728
    Abstract: A first directional control valve for switching between a first supply position and a first discharge position and a second directional control valve for switching between a second discharge position and a second supply position. A first switching mechanism permits the first directional control valve to be switched to the first supply position in a state where a second switching mechanism has switched the second directional control valve to the second discharge position. In a state where the second switching mechanism has switched the second directional control valve to the second supply position, a pressure fluid supplied to the second directional control valve at the second supply position switches the first directional control valve to the first discharge position via the first switching mechanism.

    Abstract: A hydraulic control circuit for a drive line includes first and second switching valves and first and second solenoid valves. Each switching valve is alternatively switched by a switching hydraulic pressure to connect any two of three ports. The first port of the first switching valve is connected to a hydraulic actuator. The first port of the second switching valve is connected to the second port of the first switching valve. The first solenoid valve supplies the switching hydraulic pressure to the switching valves. The second solenoid valve regulates a control hydraulic pressure supplied to the hydraulic actuator. Any one of three oil paths is communicated with the hydraulic actuator by supplying the control hydraulic pressure via the third port of the first switching valve or the second or third port of the second switching valve and supplying the switching hydraulic pressure to at least one switching valve.

  • Patent number: 9032996
    Abstract: A shaft sealing device switches a sealing state and an unsealing state of a fluid, with high sealing performance maintained, because no abrasion accompanies movement of a sealing material or a sealing member, enabling feeding a fluid at a predetermined flow rate, and adjusts the expanding rate of the sealing material with the quantity of an external electric signal and accordingly adjusts the contact face pressure to enable controlling the amount of leakage of the fluid highly precisely, so that it can be used for all applications. The shaft sealing device includes a shaft sealing body formed of a macromolecular material and made expansible or contractible, or deformable, through external electrostimuli applied to a shaft sealing portion disposed in a device body, and flow passages disposed in the shaft sealing portion for feeding the fluid leaked due to the expansion or contraction, or the deformation, of the shaft sealing body.
