Abstract
In accordance with at least one aspect of this disclosure, a system, e.g. a four-way valve system, can include a fluid source to provide fluid to a moveable component to move the moveable component between a first position and a second position. The system can include a four-way valve configured to selectively allow flow from the fluid source to enter either a first side of the moveable component through a first high pressure fluid channel or a second side of the moveable component through a second high pressure fluid channel. A controller can be operatively connected to control the valve to move between a first position and a second position, which in turn adjusts the position of the moveable component between the first position and the second position.
Claims18
A four-way valve, comprising:
- a valve body, configured to translate between a first position and a second position, including:
- a pin bounded by sealing members on opposing ends of the pin, the sealing members configured to seat within a respective juncture between one or more fluid channels;
- and
- a solenoid armature disposed on the pin between the sealing members and configured to move within a valve chamber;
- a biasing member configured to bias the valve body to the second position;
- and
- a solenoid operatively connected to the armature to control positioning of the valve body among the first and second positions based on an energized state of the solenoid.
A valve system, comprising:
- a moveable component configured to move between a first position and a second position;
- a first high pressure fluid channel fluidly connecting a fluid source to a first side of the moveable component;
- a second high pressure fluid channel fluidly connecting the fluid source to a second side of the moveable component;
- a first low pressure fluid channel fluidly connecting the first side of the moveable component to the fluid source;
- a second low pressure fluid channel fluidly connecting the second side of the moveable component to the fluid source;
- a four-way valve, configured to selectively allow flow from the fluid source to enter either the first side of the moveable component through the first high pressure fluid channel or the second side of the moveable component through the second high pressure fluid channel;
- and
- a controller operatively connected to control to move the four-way valve between a first position and a second position to adjust a position of the moveable component.
A valve system, comprising:
- a four-way valve disposed in a fluid channel, configured to selectively allow flow from a fluid channel to a first side of a moveable component and from a second side of a moveable component, or from the fluid channel to the second side of the moveable component and from the first side of the moveable component based on a state of the four-way valve;
- and
- a controller configured to control the state of the four-way valve.
