Abstract
A valve with a rotationally adjustable flow area can include a first member defining a first wall having a first opening therein, and a second member defining a second wall having a second opening therein, the first member being rotatable relative to the second member, and flow area through the valve being defined by fluidic communication between the first opening and the second opening that varies with relative rotational position between the first member and the second member.
Claims17
A rotary adjustable plate orifice valve, comprising:
- a housing including a first fluid path opening and a second fluid path opening;
- a sleeve disposed at least partially within the housing and having a sleeve opening defined by a cam surface;
- and
- a spool disposed at least partially within the sleeve and the housing and configured to rotate relative to the sleeve, the spool including:
- a plate face that abuts the cam surface;
- and
- a plate orifice defined in the plate face and configured to be positioned to be partially in fluid communication with the sleeve opening and to be partially blocked by the cam surface, wherein an amount of open area of the plate orifice that is in fluid communication with the sleeve opening changes as a function of a rotational position of the orifice relative to the cam surface;
- wherein fluid can flow between the first fluid path and the second fluid path through the plate orifice, wherein the spool extends through the sleeve opening to contact the cam surface.
A method, comprising:
- rotating a spool of a valve such that a plate orifice defined in a plate face thereof is positioned relative to a cam surface of a sleeve at a predetermined rotational position to block a predetermined amount of flow area of the plate orifice, the cam surface defines a sleeve opening, wherein the spool extends through the sleeve opening to contact the cam surface.
A valve with a rotationally adjustable flow area, comprising:
- a first member defining a first wall having a first opening therein;
- and
- a second member defining a second wall having a second opening therein, the first member being rotatable relative to the second member, and flow area through the valve being defined by fluidic communication between the first opening and the second opening that varies with relative rotational position between the first member and the second member, wherein the first member extends through the second opening to contact the first and second walls together.
