  • Patent number: 10704815
    Abstract: An air conditioning service system includes an oil receptacle configured to store an oil, a solenoid valve configured to selectively allow the oil to flow from the oil receptacle into an oil injection line, a coupling port in fluid communication with the oil receptacle through the oil injection line when the solenoid valve is in an open condition, and a flow control valve with an inlet and an outlet. The inlet is in fluid communication with the oil receptacle when the solenoid valve is in the open condition, and the outlet in fluid communication with the oil injection line when the solenoid valve is in the open condition. The flow control valve is configured such that, for a given pressure difference between the inlet and the outlet, the oil flows from through the flow control valve at a flow rate that is independent of a viscosity of the oil.

    Abstract: An impeller type water-hammer proof and silent check valve includes a shell, a sealing ring, a cowl, a flow guide body and a spring. Turbulent-flow blades are provided on the outer surface of the flow guide body. Two groups of axial-flow blades are arranged in the flow passage, and the blades are fixed on the streamline outer surface. The valve continuously converts pressure energy and kinetic energy to a torque surrounding an axial direction to the flow guide body during a process of backflow liquid flowing through the turbulent-flow blades. The valve forms a pair of torques counteracting each other as the turbulent-flow directions of the two groups of blades are opposite. The liquid pressure energy and kinetic energy are continuously and gradually converted to the torque to the flow guide body in the turbulent-flow blades, so that an abrupt impact to the valve by the water hammer is eliminated.

  • Patent number: 7628016
    Abstract: A method of effecting multi-stage supercharging in internal combustion machines comprising a supercharging system, wherein fresh air is first routed through a low-pressure compressor. At least a portion of the compressed air stream is compressed further in a high-pressure compressor, and the rest of the fresh air compressed in the low-pressure compressor is routed around the high-pressure compressor via a compressor bypass. All the fresh air is ultimately delivered to the internal combustion engine. The compressor bypass is opened or closed by a self-actuating valve in dependence on the differential pressure, the compressor bypass opening as soon as the pressure downstream from the high-pressure compressor is lower than the pressure upstream of the high-pressure compressor.

  • Patent number: 7360557
    Abstract: A check valve includes a valve housing having a first housing portion including an inlet and a second housing portion having an outlet. A poppet valve is received in the housing and includes an outer surface having a diameter greater than the diameters of the inlet and outlet. A valve guide is also received in the valve housing and defines a variable volume pressure cavity and a fluid flow path. The valve guide is adapted to provide the variable volume pressure cavity in communication with the fluid flow path. A resiliently compressible member is adapted to bias the poppet valve toward a closed position against a flow of fluid through the check valve and a low pressure force created in the variable volume pressure cavity by virtue of the fluid flow through the valve guide.

  • Patent number: 7284568
    Abstract: A safety valve unit permits its user to perform an adjustment of the valve unit in cracking pressure from the outside in an easy and an adequate manner without disassembling any part of the valve unit in a condition in which the valve unit remains inline-connected with a fluid circuit. The safety valve unit is provided with a rotary barrel member (1), in which a cracking-pressure adjusting portion (4, 5, 6, 7 and 8) is incorporated and driven by the barrel member (1) in order to adjust the cracking pressure. The barrel member (1) has its female screw portion (2) threadably engaged with a male screw portion of the cracking-pressure adjusting portion (4) that is a movable spring support (4). When the barrel member (1) is rotated, the spring support (4) is axially and linearly displaced to adjust the cracking pressure of the valve unit.

  • Patent number: 7234480
    Abstract: A telescopic snap valve assembly and method of assembling a snap valve with a liquid holding bag in a box fitting. The valve assembly includes a valve member having a lower protruding telescopic end with a raised exterior lower edge. The telescopic end of the valve member is inserted into the center opening of the fitting so that the raised exterior lower edge snaps outward and protrudes from the bottom of the fitting locking the valve member to the fitting. Tight fitting between the telescopic end of the valve and the fitting, with or without a seal member such as O-ring, and the like further seal the valve member to the fitting so that no liquid becomes trapped and/or leaks from the assembly. The assembly can use a ball check valve, and can dispense all types of liquids and fluids such as but not limited to juice with pulp without clogging the valve.

  • Patent number: 7219690
    Abstract: A two-stage fluid pressure control valve has five components. An inlet socket with separate fluid flow orifices sealably engages an outlet socket which also has separate fluid flow orifices. A pressure check piston having a fluid flow orifice along its longitudinal central axis slidably engages the inlet socket and the outlet socket. A spring located along the central axis of the outlet socket biases the pressure check piston in an open position, allowing fluid to flow through all orifices. Fluid flow through the control valve may impact the pressure check piston to overcome the spring force, moving the pressure check piston to a closed position, whereby fluid flows only through the orifice in the pressure check piston.

  • Patent number: 7171981
    Abstract: A flow control valve has a ball and an annular seat providing a positive stop for automatically preventing flow through the valve when a line downstream has been broken. The flow control valve is useful for interior applications in which seepage through the valve would be unacceptable and in which both hot and cold water lines need to be protected. A magnet may aid in positioning the ball. Sensors may be used to detect positions of the ball. A flow control system that includes the flow control valve may include any of a variety of interchangeable components for facilitating incorporation of the flow control valve in a water or other fluid line. Another embodiment includes a mechanism for detecting and stopping flow due to slow leaks.

  • Patent number: 7069946
    Abstract: A slow-release check valve for a pneumatic system including a compressed gas source and a pneumatic device includes a body with a proximal, supply end and a distal, power end. Supply and power couplings are mounted on the body supply and power ends respectively and are adapted for coupling with a compressed gas source and a pneumatic device respectively. The body includes a passage with a frusto-conical configuration with a minimum-diameter supply end adjacent to the supply coupling and a maximum-diameter power end adjacent to the power coupling. A ball is movably located within the passage and engages the body in a closed position. The ball is biased towards its closed position by a spring. For power operation the ball is in an open position whereby gas flows around same. Disconnecting the hose causes the ball to move to its closed position and allows compressed gas to slowly dissipate from the disconnected hose whereby fishtailing is avoided.

  • Patent number: 6988510
    Abstract: A free floating disc check valve is provided by the present application. The check valve includes a seal disc having an integral truncated torroidal shaped portion. The torroidal shaped portion provides structural rigidity to the seal disc to minimize deflection of the disc under higher differential fluid pressures. The torroidal shaped portion of the disc cooperates with finger-shaped projections inside the valve body to limit lateral displacement of the disc relative to the axial flow of the fluid. The torroidal shaped portion and the flat portion of the disc form a cup shape that creates a hydrodynamic force that assists in moving the disc to an opened or closed position. The seal disc is made of an elastomeric material that is coated with a dry film lubricant.
