Abstract
A valve assembly includes a valve body having a first port and a second port, the first port forms a fluid pathway from a first surface of the valve body to a second surface of the valve body, and the second port forms a fluid pathway from the second surface of the valve body to a third surface of the valve body. The valve assembly also includes a first plate having a first blocking member, the first blocking member configured to block the first port at the first surface of the valve body when the first plate is in a first closed position. The valve assembly also includes a second plate having a second blocking member, the second blocking member configured to block the second port at the second surface of the valve body when the second plate is in a second closed position.
Claims20
A valve assembly, comprising:
- a valve body having a first port and a second port, the first port forms a fluid pathway from a first surface of the valve body to a second surface of the valve body, and the second port forms a fluid pathway from the second surface of the valve body to a third surface of the valve body;
- a first plate having a first blocking member attached to the first plate, the first blocking member configured to block the first port at the first surface of the valve body when the first plate is in a first closed position;
- and
- a second plate having a second blocking member attached to the second plate, the second blocking member configured to block the second port at the second surface of the valve body when the second plate is in a second closed position;
- wherein when the first plate is in a first open position, a biasing member keeps the first blocking member at least partially disposed in the first port.
A method of forming a valve assembly, comprising:
- providing a valve body with a port that forms a fluid pathway from a first surface of the valve body to a second surface of the valve body, wherein the port at the first surface forms a seat;
- disposing a blocking member in the seat, the blocking member only free to rotate about an axis parallel with the port;
- and
- attaching a plate to the blocking member disposed in the seat.
