Abstract
The present invention is directed to a bypass valve assembly having a valve housing with an inlet port, outlet port, and bypass port all formed within the valve housing. A valve member is operably connected to the valve housing and includes a first valve plate and second valve plate that face in substantially opposite directions from each other. The first valve plate articulates to form a tight barrier with the outlet port when the valve member is in a first position, and the second valve plate articulates to form a tight barrier with the bypass port when the valve member is in a second position.
Claims22
A valve assembly, comprising:
- a valve housing;
- a first port formed in said valve housing;
- a second port formed in said valve housing;
- a third port formed in said valve housing;
- said first, second, and third ports operable to receive or deliver a fluid medium flow;
- a valve member operably connected to said valve housing for controlling a fluid medium flow associated with two of the three ports, said valve member including a first valve plate and a second valve plate facing in substantially opposite directions from each another, wherein said first valve plate articulates in radial, axial, and multi-axis-angular directions to selectively form a tight barrier with one of said ports to block the fluid medium flow through said port and said second valve plate articulates in radial, axial, and multi-axis-angular directions to selectively form a tight barrier with another of said ports to block the fluid medium flow through said port, or said valve member pivots to distribute the fluid medium flow therebetween.
A bypass valve assembly comprising:
- a valve housing including an inlet port, an outlet port, and a bypass port;
- a first seating surface surrounding an opening of said outlet port;
- a second seating surface surrounding an opening of said bypass port;
- and
- a valve member disposed inside said valve housing, said valve member comprising first and second valve plates facing in substantially opposite directions from each other and slidably connected to a pivot arm, wherein a pin operably couples said first and second valve plates and said first and second valve plates can pivot 360 degrees about the circumference of said pin and slide along the longitudinal axis of said pin;
- wherein said pivot arm pivots said valve member to a first position and said first valve plate articulates relative to said first seating surface to inhibit substantially all of a fluid medium from flowing through said outlet port, or said valve member pivots to a second position and said second valve plate articulates relative to said second seating surface to inhibit substantially all of said fluid medium from flowing through said bypass port, or said valve member pivots to distribute said fluid medium therebetween.
A valve arrangement comprising:
- a valve housing having an inlet port, an outlet port, and a bypass port;
- an upstream path connected to said valve housing through said inlet port;
- a downstream path connected to said valve housing at said outlet port;
- a bypass path connected to said valve housing at said bypass port, wherein said bypass path reconnects to said downstream path at a junction downstream of said valve housing;
- a valve member operably connected to said valve housing, said valve member including a first valve plate and a second valve plate facing in substantially opposite directions from each other, wherein said first valve plate articulates to form a tight barrier with said outlet port when in a first position, and said second valve plate articulates to form a tight barrier with said second bypass port when in a second position;
- a structure located in said downstream path between said valve housing and said junction, wherein said bypass path is used to direct fluid around said structure.
A method of assembling a valve assembly comprising:
- providing a first housing comprising a first port and an opening defined by a first flange;
- providing a second housing comprising a second port, third port, a passage, and an opening defined by a second flange;
- providing a first valve plate, a second valve plate, a pivot arm including a first end operable to receive a shaft, and a pin;
- assembling a valve member by slidably connecting said pivot arm to said first and second valve plates disposed in substantially opposite directions and inserting a pin through an aperture of at least one of said first or second valve plates;
- inserting said valve member through said opening defined by said second flange;
- locating said valve member in a position to pivot between said first port, and one of said second or third ports, and any position therebetween;
- inserting said shaft partly through said passage and rotatably connecting said shaft to said first end of said pivot arm;
- providing a lever assembly including a lever, washer, and a lever pivot, wherein said lever is operably connected to said shaft;
- operably connecting said first housing to said second housing, wherein said flange of said first housing is aligned with said second flange of said second housing;
- and
- providing an actuator operably connected to said lever assembly, said actuator manipulating said lever assembly to rotate said shaft, wherein said valve member pivots to a first position for restricting a fluid medium from flowing through said first port, or said valve member pivots to a second position for restricting said fluid medium from flowing through said second or third port or pivots to any position therebetween.
