Abstract
A valve (200) for routing a fluid includes a housing (220) having an inlet (222) and at least one outlet port (224). A valve member (218) is located in the housing (220). The valve (218) member has a wall (232) enclosing a cavity (230). A plurality of inlet openings (234) is formed in the wall (232). At least one of the plurality of inlet openings (234) fluidly connects the inlet (222) of the housing (220) with the cavity (230), and the at least one outlet port (224) may be selectively fluidly connected to the cavity (230).
Claims17
A valve for routing a fluid, comprising:
- a housing having an inlet and at least one outlet port;
- a valve member disposed in the housing, the valve member having:
- a wall enclosing a cavity;
- a plurality of inlet openings disposed in the wall, wherein at least one of the plurality of inlet openings fluidly connects the inlet of the housing with the cavity;
- and
- wherein the at least one outlet port is selectively fluidly connected to the cavity.
A valve assembly, comprising:
- a housing having an inlet, a first outlet, and a second outlet;
- a hollow valve member disposed in the housing, wherein the hollow valve member includes a cavity therein;
- at least one inlet opening in the valve member;
- at least one outlet opening disposed at a distal end of the valve member;
- wherein when the valve is disposed in a first position within the housing, a first flow path may be defined between the inlet, the at least one inlet opening, the cavity, the at least one outlet opening, and the first outlet, and wherein a first seal is defined at a first interface between the valve member and a second header that fluidly isolates the first flow path from the second outlet.
A method for a method of directing a flow of fluid from an inlet to one or more outlets, comprising the steps of:
- receiving a flow of fluid into a housing through an inlet port;
- admitting the flow of fluid into a cavity of a valve member through at least one opening in the valve member;
- expelling the flow of fluid from the cavity through an open end of the cavity;
- passing the flow of fluid over a tapered surface that is disposed on a lip section of the valve member that surrounds the open end;
- routing the flow of fluid out of the housing through a first outlet port.
