Abstract
A grid valve may include an annular stationary plate having a first annular surface, and an annular rotatable plate disposed on the annular stationary plate and rotatable relative to the annular stationary plate. The annular rotatable plate may have a second annular surface, and each of the annular stationary plate and the annular rotatable plate may define a plurality of holes in the respective annular surfaces thereof. The grid valve may further include a first magnet disposed on the first annular surface and a second magnet disposed on the second annular surface such that the first magnet repels the second magnet.

9. A grid valve, comprising:
-
an annular stationary plate defining a plurality of stationary plate holes circumferentially disposed in a first annular surface thereof, such that the plurality of stationary plate holes encircle an opening defined in the annular stationary plate, the opening configured to receive a rotatable shaft therethrough; and an annular rotatable plate disposed on the annular stationary plate and rotatable relative to the annular stationary plate, the annular rotatable plate defining a plurality of rotatable plate holes in a second annular surface thereof contacting the first annular surface, the plurality of rotatable plate holes including a first set of rotatable plate holes and a second set of rotatable plate holes, wherein the first set of rotatable plate holes has a first circumferential extent and the second set of rotatable plate holes has a second circumferential extent different from the first circumferential extent, and the annular rotatable plate is configured to permit working fluid to pass through the plurality of stationary plate holes and the plurality of rotatable plate holes in a first predetermined sequence; a first magnet disposed on the first annular surface; and a second magnet disposed on the second annular surface such that the first magnet repels the second magnet. - View Dependent Claims (10, 11, 12, 13)
