Abstract
A multi-port valve assembly for controlling the flow of fluid through a plurality of outlet ports. A valve housing defines a common inlet and a plurality of outlet ports. A valve member corresponds to each outlet port for controlling fluid flow through the respective port. Each valve member is independently adjustable for separately adjusting fluid flow characteristics through its respective port. All of the valve members are conjointly movable for controlling fluid flow through all the outlet ports simultaneously.
Claims24
A multi-port valve assembly for controlling the flow of fluid through a plurality of outlet ports, comprising:
- a valve housing defining inlet means and said plurality of outlet ports;
- a valve member corresponding to each outlet port for controlling fluid flow through the respective port;
- menas for independently adjusting each valve member for separately adjusting fluid flow characteristics through the respective port including first, coarse adjustment means and second fine adjustment means;
- and
- means on the housing for conjointly moving the valve members for controlling fluid flow through all the outlet ports simultaneously.
A multi-port valve assembly for controlling the flow of fluid through a plurality of outlet ports, comprising:
- a valve housing defining inlet means and said plurality of outlet ports;
- a valve member corresponding to each outlet port for controlling fluid flow through the respective port;
- first, coarse adjustment means for varying a set position of each valve member relative to the moving means, the set position being defined by discrete calibration means between the valve member and the moving means;
- second, fine adjustment means for independently varying the effective port size of each outlet port for any given operative set position of the respective valve member;
- and
- means on the housing for conjointly moving the valve members for controlling fluid flow through all the outlet ports simultaneously, said coarse adjustment means being operatively associated between the moving means and each respective valve member.
A multi-port valve assembly for controlling the flow of fluid through a plurality of outlet ports, comprising:
- a valve housing defining inlet means and said plurality of outlet ports, each port including a liner;
- a needle valve movable in an axial direction toward and away from each respective outlet port for controlling fluid flow through that outlet port;
- and
- adjustment means for independently varying the effective port size of each outlet port for the respective needle valve including means for independently adjusting the axial position of each liner.
