  • Patent number: 10724811
    Abstract: A bypass system has a source of a fluid to be cooled and a heat exchanger for selectively cooling fluid. A piston is moveable along an axis allowing movement of a valve poppet toward and away from the valve seat. The piston contacts a boot. A wax element is disposed in a chamber, such that the wax element expands as a temperature of the fluid to be cooled increases, and causes the valve poppet to move against the valve seat. The boot has wax separator structures. A bypass valve is also disclosed.

  • Patent number: 10723609
    Abstract: Containers of the same or different size are filled with a non-viscous fluid at discrete stations, each container being filled independently of each other container. Multiple containers of the same or different size are positioned at multiple discrete stations, each container being at a different station. A non-viscous fluid is flowed into a container to a desired level. The level is sensed with a level sensor and the fluid flow stopped at the desired level. The fluid flow is reversed to prevent fluid dripping when a filled bottle is removed.

  • Patent number: 10655742
    Abstract: A fluid injection device (10) for injecting a dispensible fluid such as a liquid sealant (24) into an air conditioning or refrigeration system or the like, includes a tube (12, 12?, 12?) containing the fluid sealant in a storage chamber (26, 26?, 26?). Outlet valves conventionally used at the tube outlet are replaced with a rupturable membrane (28, 28?, 66). Means to rupture the membrane may comprise a puncture tool (32, 50), or the membrane may be designed to burst under pressure imposed on it in use. Use of membrane (28, 28?, 66) at the outlet of device 10 avoids problems caused by even very slight leakage of fluid sealant past an outlet valve. The fluid injection device (10) is used by connecting the tube inlet to a high pressure zone of the system and connecting the tube outlet to a low pressure zone of the system.

  • Patent number: 10654177
    Abstract: A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.
