Abstract
A fluid flow metering rotary valve body is provided that includes a central axis, and at least one lobe having at least one fluid opening. At least one fluid throttle is formed on a perimeter surface of the at least one fluid opening. The fluid throttle can have at least one blind void or at least one protrusion and can facilitate various flow strategies, including a decreasing fluid flow with increasing overlap between the fluid opening and a fluid port. The at least one protrusion can extend to various depths to accommodate different fluid openings and injection molding strategies.
Claims17
A fluid flow metering rotary valve body comprising:
- a central axis;
- at least one lobe having at least one fluid opening, the at least one fluid opening including:
- a perimeter surface;
- at least one fluid throttle formed on the perimeter surface, the at least one fluid throttle comprising at least one protrusion having a width less than a width of the at least one fluid opening;
- and,
- a bottom surface;
- and,
- a depth of the at least one fluid throttle extending to the bottom surface.
A fluid flow metering rotary valve body comprising:
- a central axis;
- at least one lobe having at least one fluid opening, the at least one fluid opening including:
- a perimeter surface;
- at least one fluid throttle formed on the perimeter surface, the at least one fluid throttle comprising at least one protrusion, and, the at least one protrusion forming at least one channel;
- and,
- the at least one fluid opening is configured to provide:
- (i) an incoming fluid path defined by a first portion of the at least one fluid throttle that overlaps a fluid port;
- and, (ii) an exiting fluid path through a second portion of the at least one fluid throttle that does not overlap the fluid port.
