  • Patent number: 11781670
    Abstract: A rocker valve comprising a rocker valve mechanism in a valve body. The mechanism comprises a single pivot arm to which first and second plungers are pivotally fixed to act in opposition. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports and having a first sealing region attached to a plunger head of the first plunger and a second sealing region attached to a plunger head of the second plunger. When the single pivot arm is pivoted relative to the valve body, a rotation of at least one of the first and second plungers about its respective fixed pivot is constrained solely by the flexible seal member such that a lateral position of the plunger head is automatically adjusted by the flexible seal member to balance tensile forces in the flexible seal member around the plunger head.

  • Publication number: 20190353272
    Abstract: The present invention provides a rocker valve comprising a valve body including first and second fluid ports and a rocker valve mechanism in the valve body. The mechanism comprises a single pivot arm rotatable relative to the valve body, and first and second plungers pivotally fixed to the single pivot arm. The second plunger acts in opposition to the first plunger when the single pivot arm is pivoted relative to the valve body. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports. The flexible seal member has a first sealing region attached to the first plunger and a second sealing region attached to the second plunger and is movable by the first and second plungers between a first position in which the first fluid ports is closed by the first sealing region, and a second position in which the second fluid port is closed by the second sealing region.

  • Patent number: 10344881
    Abstract: Devices and a method are described herein for fixing a valve to a base via a single point on the base. The valve may be fixed to the base using a plate inserted through a slot in the base and along a face of the valve body. The plate may include a head at one end to retain the plate in the slot. A valve may also be fixed to a base using a combination of a brace and a screw that threads into the base. The brace may include a lip that fits into a grove on the shaft of the screw. The valve body may include a lip to retain the combined screw and brace when the screw is not threaded into the base.

  • Patent number: 8540208
    Abstract: A bistable valve (100) is provided according to an embodiment of the invention. The bistable valve (100) includes an armature (108) movable to selectively block and unblock at least a first port (104) and a biasing device (112) configured to provide a first biasing force that biases the armature (108) toward a first position blocking the first port (104). The bistable valve (100) further includes a plurality of substantially radially magnetized permanent magnets (114) configured to provide a second biasing force to the armature (108) substantially opposite to the first biasing force and an electromagnetic coil (116) configured to generate a third biasing force when energized with a first current polarity. The third biasing force is substantially opposite to the first biasing force and in combination with the second biasing force overcomes the first biasing force and moves the armature (108).
