Abstract
In accordance with at least one aspect of this disclosure, a flow control device can include, a first plate having one or more windows defining a flow path therethrough, a second plate configured to abut the first plate, and an actuator operatively connected to one or more of the first plate and/or the second plate. The actuator can be configured to drive the first plate and/or the second plate relative to one another to enlarge or reduce the flow path through the one or more windows in the first plate.
Claims16
A flow control device, comprising:
- a first plate having one or more windows defining a flow path therethrough;
- a second plate configured to abut the first plate and the second plate having a face;
- and
- an actuator operatively connected to one or more of the first plate and/or the second plate, configured to drive the first plate and/or the second plate relative to one another to enlarge or reduce the flow path through the one or more windows in the first plate, wherein the second plate includes one or more protrusions smaller than the face of the second plate and configured to align with and insert into and through the one or more windows of the first plate, wherein in a closed state, the one or more protrusions are configured to block the flow path through the one or more windows in the first plate.
1 more element
A method comprising:
- controlling, with a piezoelectric actuator, a flow control device disposed in a fluid system, wherein controlling includes, driving one or more of a first plate which includes one or more windows and/or a second plate which includes a face of the flow control device to allow flow to pass through the one or more windows in the first plate and through or more windows in the second plate or around one or more protrusions in the second plate, the one or more protrusions smaller than the face of the second plate and configured to align with, and insert into and through the one or more windows of the first plate.
