Abstract
A valve assembly includes multiple valves operatively connected with a single valve actuator operable to control and restrict the corresponding positions of each of the multiple valves.
Claims19
A valve assembly comprising:
- a valve body defining a first end passage extending to a first end port, a second end passage extending to a second end port, an internal through passage extending between the first and second end passages, and a bleed passage extending to a vent port;
- a first valve element disposed in the first end passage and defining a first valve passage;
- a second valve element disposed in the second end passage and defining a second valve passage;
- a third valve element disposed in the bleed passage and defining a third valve passage;
- and
- a valve actuator operatively connected with each of the first, second, and third valve elements, the valve actuator being movable between:
- a first position corresponding to an open flowpath configuration in which the first and second valve elements are in an open position permitting fluid flow between the first end port and the second end port, and the third valve element is in a closed position blocking flow between the internal through passage and the vent port;
- a second position corresponding to a bleed configuration in which the first and second valve elements are in a first closed position blocking flow between the first and second end ports and the internal through passage, with the first and second valve passages being open to the internal through passage, and the third valve element is in a first switching position permitting fluid flow between the internal through passage and the vent port;
- and
- a third position corresponding to a downstream vent configuration in which the first and second valve elements are in a second closed position blocking flow between the first and second end ports and the internal through passage, with the second valve passage being open to the second end port, and the third valve element is in a second switching position permitting fluid flow between the internal through passage and the second valve passage.
7 more elements
A valve assembly comprising:
- a valve body;
- a first valve element assembled with the valve body and rotatable about a first valve axis;
- a second valve element assembled with the valve body and rotatable about a second valve axis perpendicular to the first valve axis;
- and
- a valve actuator operatively connected with each of the first and second valve elements, the valve actuator being rotatable about an actuator axis for rotation of the first and second valve elements between first and second positions;
- wherein the valve actuator is operatively connected to the second valve element by a gear mechanism;
- and
- wherein the gear mechanism comprises a first gear wheel rotatable about a first gear axis codirectional with the first valve axis, a second gear wheel rotatable about a second gear axis codirectional with the second valve axis, and a gear rack having a first row of teeth operatively connected with the first gear wheel and a second row of teeth operatively connected with the second gear wheel.
