  • Patent number: 10247068
    Abstract: An oil separating module for an internal combustion engine, including: an oil separator, an oil return arranged such that separated oil can flow through the oil return to an oil sump, a mounting, and a non-return valve having: a valve housing having a throughbore with a first end opening and a second end opening, and a valve body movably mounted in the valve housing such that the valve body transitions between an open position and a closed position. When the first end opening is above the second end opening, the valve body automatically transitions to, or remains in, the closed position when a second end opening pressure is greater than a first end opening pressure by at least a threshold pressure difference, and the valve body automatically transitions to, or remains in, the open position when the second pressure is not greater than the first pressure by at least the threshold pressure difference.

  • Patent number: 10242785
    Abstract: A valve for metering fluid has an electromagnet for actuating a valve needle controlling a metering opening. The electromagnet generates, upon current flow, a magnetic flux that proceeds via an outer pole, a hollow-cylindrical inner pole, an armature displaceable on an armature guidance region embodied on the valve needle, and a working air gap delimited by the armature and inner pole. Disposed fixedly on the valve needle is an entraining element that penetrates axially displaceably into an entraining element guidance region embodied in the inner pole and has a radial stop shoulder for the armature which delimits a take-up travel or pre-stroke travel. The entraining element is extended into an additional inner pole having a pole surface formed by the stop shoulder, and is embodied magnetically conductively and a magnetic flux between the armature and valve needle is suppressed by way of a magnetically nonconductive material.

  • Patent number: 10221955
    Abstract: One embodiment relates to a valve device. The valve device includes: a valve case; a valve element slidably disposed within a valve chamber defined in the valve case; and a positive pressure spring configured to urge the valve element toward a valve seat in the valve case. The valve element includes an outer circumferential portion having a predetermined length extending along an inner circumference of the valve chamber. The outer circumferential portion includes plural opening portions. And, ribs project from the inner circumference of the valve chamber to enter into the opening portions, thereby limiting movement of the positive pressure spring in a radial direction.

  • Patent number: 10215338
    Abstract: A system for discharging hydrogen from two or more hydrogen storage vessels (1A, 1B, 1C) containing solid hydrogen storage material. The system includes at least one hydrogen supply line for connecting the hydrogen storage vessels to a hydrogen demand (3), and energy delivery system (6A, 6B, 6C) to provide heat to the hydrogen storage material in each hydrogen storage vessel to desorb hydrogen from the solid hydrogen storage material, and one or more supply connection conduits (4A, 4B, 4C) for connecting the supply line of lines to the hydrogen storage vessels (1A, 1B, 1C). Each supply connection conduit has a backflow prevention device (5A, 5B, 5C) to prevent hydrogen in the supply line from flowing back into the hydrogen storage vessels (1A, 1B, 1C). Also disclosed is a system for delivering a supply of hydrogen to a hydrogen supply line including a control system (7) to determine the timing of activation of an energy delivery system based (6A, 6B, 6C) on the hydrogen demand in the hydrogen supply line.

  • Patent number: 10072766
    Abstract: A check valve including a valve member movable with a passage in a housing is disclosed. A biasing means applies a biasing load to the valve member to urge the valve member into engagement with a seating surface within the passage to control fluid flow. An environmental seal member is secured to the valve member by a retainer member. The retainer member includes a lip elastically deflectable by the environmental seal member upon compression and/or deflection of the environmental seal member. When the valve member engages the seating surface, the environmental seal member engages the seating surface to compress and/or deflect the environmental seal member, deflects the lip of the retainer member into engagement with the seating surface. Extrusion of the environmental seal member between the retainer member and the seating surface can be reduced and the engagement between the lip and the seating surface may be a sealing engagement.
