Abstract
Valves. At least some of the example valves include: a valve body; a valve housing; and a piston that defines a proximal end and a distal end, the piston disposed in a piston bore of the valve housing. The valve defines a closed orientation by a first rotational orientation of the valve housing relative to the valve body, and the valve defines an open orientation by a second rotational orientation of the valve housing distinct from the first rotational orientation.
Claims26
A valve assembly comprising:
- a valve body that comprises
- a first counter bore with a first diameter and a first central axis;
- a second counter bore disposed within the first counter bore, the second counter bore having a second central axis parallel to and offset from the first central axis, and a second diameter smaller than the first diameter;
- an inlet port fluidly coupled to the first counter bore;
- and
- an outlet port fluidly coupled to the second counter bore;
- a valve housing comprising
- a circular stem member that defines a third central axis;
- a piston receptacle member that defines a piston bore, the piston bore defines a fourth central axis perpendicular to the third central axis;
- a flow passage defined in the circular stem member, the flow passage fluidly coupled to the piston bore;
- the circular stem member disposed within the second counter bore;
- the piston receptacle member disposed within the first counter bore;
- and
- the second and third central axis are coaxial;
- a piston that defines a proximal end and a distal end, the piston disposed in the piston bore of the valve housing;
- an eccentric ring that defines a fifth central axis, the eccentric ring disposed within the first counter bore, the eccentric ring circumscribes the valve housing, the proximal end of the piston coupled to the eccentric ring, and the first and fifth central axis are coaxial;
- the valve assembly defines a closed orientation by a first rotational orientation of the piston and piston bore relative to the second counter bore, and the valve assembly defines an open orientation by a second rotational orientation of the piston and piston bore relative to the second counter bore, the second rotational orientation distinct from the first rotational orientation.

- controlling flow of a fluid through a valve by
- turning a valve housing about a housing axis, the turning relative to a stationary valve body;
- and thereby
- translating a piston along a piston axis, the piston within a piston bore defined in the valve housing, the piston axis perpendicular to the housing axis;
- and
- turning an eccentric ring about a ring axis, the eccentric ring encircles the valve housing, and the ring axis parallel to and offset from the housing axis, the piston coupled to the eccentric ring.
