Abstract: A switching valve for an air spring arrangement of a motor vehicle, which switching valve has a valve housing arrangement which, in the installed state, is arranged between a first air volume and a second air volume. A valve closing member arrangement is actuatable by an actuator is provided such that the valve closing member arrangement, in a first position, fluidically connects the first air volume to the second air volume and, in a second position, fluidically separates the first air volume from the second air volume. The valve closing member arrangement is designed as a rotary slide arrangement. A rotary slide member with first openings is provided between two valve closing bodies, wherein, in the first position, the first openings correspond with second openings of the valve closing body such that a fluidic connection can be produced between the first and the second air volume.

Abstract: A diaphragm valve includes: a valve body having formed therein a first valve chamber, a second valve chamber and a communication passage communicating between the two valve chambers; a valve seat formed in the communication passage; a valve mechanism including a diaphragm supporting a valve element that comes in contact with and separates from the valve seat and a second diaphragm; a pressurizing unit being configured to pressurize the first diaphragm so as to press the valve element against the valve seat; and a bonnet for holding an outer peripheral part of the second diaphragm between the bonnet and the valve body. The pressurizing unit is configured as a single integrated unit holding therein a movable body that moves in conjunction with the valve element via a stem.

Abstract: A safety apparatus for containing a release of energy from a tension stud of a rotor assembly. The safety apparatus includes a containment member configured to pivot about a pivot location. The containment member includes a tail located on a first side of the pivot location, an elongate region on a second side of the pivot location, the elongate region defining a longitudinal axis and an arm located towards a distal end of the elongate region and projecting away from the longitudinal axis. The containment member is configured to be connected to a tool apparatus. In use, the containment member is configured to pivot between an open position and a containment position in which the arm overlaps with at least part of the tool apparatus in the direction of the longitudinal axis of the elongate region to contain the load energy within the safety apparatus.

Abstract: The invention relates to a check valve which in one embodiment is a modular three-piece valve assembly with easily serviceable and replaceable internal parts, and in another embodiment is a nodular two-piece valve with easily serviceable and replaceable internal parts. In each embodiment, the check valve includes a valve body of two or more pieces detachably attached to each other, and a poppet assembly for sealing the valve removably located within the overall body formed by the attachment of those detachably attached pieces.

Abstract: A butterfly valve comprises: a body including a valve opening; and a flapper rotatably mounted about a rotation axis so as to be movable relative to the valve opening. The flapper is rotatable at least 180° about the rotation axis so that the flapper is movable to at least one fully opened position, at least one fully closed position 90° apart from the fully opened position, and a third position, either fully opened or fully closed, 180° from the other like position. In one embodiment the flapper is rotatable at least 360° about the rotation axis so that the flapper is movable to each of two opened positions 180° apart, and two closed positions 180° apart from each other and 90° and 270° apart from each of the fully opened positions. The valve can be easily calibrated and controlled, and cleaned to extend the useful service life between cleanings.

Abstract: A valve system for a container or vat, such as a food cooking vat. The valve system includes a valve body and stem having a valve head with a sealing member. The valve body has an outlet configured to be in fluid communication with the vat, and the sealing member is in fluid communication with the outlet and the chamber and is selectively operable between a discharge position, allowing the vat's contents to drain from the chamber, and a closed position, allowing the contents to remain in the chamber. The sealing member preferably is comprised of polymer and has an O-type sealing ring interposed between a first portion and a second portion, where the diameter of the second portion is smaller than the diameter of the first portion. Embodiments may also include a snap-fit connection of the sealing member to the valve head.

Abstract: A valve system for attachment to a food cooking vat. The valve system includes a valve body and stem, with the stem including a valve head having a sealing member connected thereto. The valve body has an outlet configured to be in fluid communication with the food cooking vat, and the sealing member is in fluid communication with the outlet and the chamber and is selectively operable between a discharge position, for allowing the food to drain from the chamber, and a closed position, for allowing the food to remain in the chamber. The sealing member preferably includes polymer and has a first portion of generally frusto-conical shape and a second portion of generally frusto-conical shape generally co-axial with the first portion.

Abstract: The present invention provides a failure protection apparatus including an air source providing air having an air pressure, a first valve in fluid communication with the air source permitting fluid communication of a control fluid between a first fluid port and a second fluid port when the air pressure is at least a minimum air pressure and preventing fluid communication of the control fluid between the first fluid port and the second fluid port when the air pressure is below the minimum air pressure, a second valve in fluid communication with the air source preventing communication of air between an air inlet and an air outlet when the air pressure is at least the minimum air pressure and permitting communication of air between the air inlet and the air outlet when the air pressure is below the minimum air pressure, a third valve in fluid communication with the air source permitting communication of air to a third valve outlet when the air pressure is at least the minimum air pressure and preventing communic

Abstract: A retrofit valve for primarily for use in conventional domestic, agricultural and commercial water taps. The valve has a seat (10) located in a passageway between a water inlet (11) and a water outlet (12). A spherical sealing member (13) is arranged to seal against the fluid inlet side of the seat, and a plunger (12) is provided for moving the sealing member off the seat.

Abstract: A flow reversal control valve for use in a fuel cell. The valve includes a housing having a first end and a second end disposed along a longitudinal axis. The valve also includes a wall that defines a first passage in fluid communication with a second passage. The first passage is disposed proximate to the first end and the second passage is disposed proximate to the second end. The valve further includes a chamber in fluid communication with the first and second passages. There are flow flutes formed in the chamber. A seal is disposed in the chamber and coupled to at least one of the first and second passages. The seal has an elastomeric member disposed on a planar surface transverse to the longitudinal axis. There is a closure member disposed in at least one of the first passage, second passage and the chamber.

Abstract: There are provided a fluid flow control valve and an orifice for a fluid flow control valve. The orifice defines two seats against which a diaphragm of the valve can be urged. Each seat defines a particular contour, including one or more channels, slots, and or protrusions that form flow control passages through which fluid flows between the diaphragm and the orifice. The orifice can be configured in either of two orientations so that either seat can be disposed toward the diaphragm. As the pressure differential across the valve increases, the diaphragm is urged more firmly against the seat facing the diaphragm and the diaphragm partially closes the flow control passages, thereby regulating the flow to a substantially uniform volumetric rate. The contours of the two seats can be the same, or each seat can be different to provide a unique controlled flow rate.
