Abstract
A filter assembly includes a filter head, a port, a fitting, and a diffuser. The port extends from a portion of the filter head and defines a channel for fluid to flow into or out of the filter head. The fitting first end is attachable to the port and the fitting second end is attachable to a filtration system component. The diffuser is positionable within the channel of the port and comprises an inner surface and an outer surface. The inner surface defines an inner conical hollow region that extends at a nonzero angle between the inner conical hollow region first end and the inner conical hollow region second end such that a first inner diameter of the diffuser at the inner conical hollow region first end is smaller than a second inner diameter of the diffuser at the inner conical hollow region second end.
Claims22
A filter assembly, comprising:
- a filter head;
- a port extending from a portion of the filter head and defining a channel for fluid to flow into or out of the filter head, the port comprising a ledge formed within the channel;
- a fitting extending between a fitting first end and a fitting second end thereof, the fitting first end attachable to the port and the fitting second end attachable to a filtration system component;
- and
- a diffuser positionable within the channel of the port and between the ledge of the port and the fitting first end, the diffuser comprising an inner surface and an outer surface, the inner surface defining an inner conical hollow region extending between an inner conical hollow region first end and an inner conical hollow region second end, the inner surface extending at a nonzero angle relative to the direction of flow between the inner conical hollow region first end and the inner conical hollow region second end such that a first inner diameter of the diffuser at the inner conical hollow region first end is smaller than a second inner diameter of the diffuser at the inner conical hollow region second end.
A filter assembly, comprising:
- a filter body;
- a port extending from a portion of the filter body and defining a channel for fluid to flow into or out of the filter body, the port comprising a ledge formed within the channel, and being attachable to a fitting first end of a fitting;
- and
- a diffuser positionable within the channel of the port and between the ledge of the port and the fitting first end, the diffuser comprising an inner surface and an outer surface, the inner surface defining an inner conical hollow region extending between an inner conical hollow region first end and an inner conical hollow region second end, the inner surface extending at a nonzero angle relative to the direction of flow between the inner conical hollow region first end and the inner conical hollow region second end such that a first inner diameter of the diffuser at the inner conical hollow region first end is smaller than a second inner diameter of the diffuser at the inner conical hollow region second end.
