Multiposition selector valve

A multiposition selector valve of the rotary type comprising:

• a valve body having a single inlet port and a plurality of outlet ports, the ports opening at the bottom of a circular bore provided on one face of the valve body, the inlet port being located at the center of the bore, the outlet ports being arranged around the inlet port at equal radial distances from the center of the bore;
• a flat metal disk of a diameter slightly less than the diameter of the bore, the disk being slidably received in the bore, the disk including a central aperture aligned with the inlet port and a plurality of outer apertures each generally aligned with a respective one of the outlet ports, the disk being removable from the valve body to facilitate maintenance of the valve.
• a check valve assembly having an inlet and an outlet, the check valve assembly being mounted within the central aperture of the metal disk, the inlet of the check valve being connected in fluidtight relationship to the inlet port;
• a rotor member rotatably mounted on the valve body for rotation on the center axis of the central aperture of the metal disk, the rotor member providing a conduit having an inlet end and an outlet end, the inlet end of the conduit being connected in fluidtight relationship to the outlet of the check valve assembly, the outlet end of the conduit being connectable in fluidtight relationship to the outer apertures of the metal disk via a spring-biased seal member carried by the rotor and slidably engageable in fluidtight relationship with the metal disk as the rotor member is rotated, the seal member being forced by spring-biasing against that side of the disk adjacent the rotor member;
• a cap member fastened to the valve body and generally covering the rotor and the metal disk;
• a push rod member having an exposed end portion extending through the cap, the push rod member sliding axially along the axis of rotation of the rotor member to open the check valve assembly, a portion of the rotor extending through the cap member and surrounding the exposed end portion of the push rod, the said extended portion of the rotor acting as a linear movement permitting support bushing for the push rod;
• and
• a handle pivotally mounted on the said extended portion of the rotor, the handle rotating the rotor member and moving the push rod to open the check valve and thus provide fluid communication between the inlet port and a selected outlet port dependent on the position of the rotor member.

A multiposition selector valve of the rotary type comprising:

• a valve body having at least one inlet port and a plurality of outlet ports;
• a flat metal disk mounted on the valve body, the disk including a central aperture aligned with the inlet port and a plurality of outer apertures each generally aligned with a respective one of the outlet ports, the disk being removable from the valve body to facilitate maintenance of the valve;
• a check valve assembly having an inlet and an outlet, the check valve assembly being mounted adjacent the central aperture of the metal disk, the inlet of the check valve being connected in fluidtight relationship to the inlet port;
• a rotor member rotatably mounted relative to the valve body for rotation on the center axis of the central aperture of the metal disk, the rotor member providing a conduit having an inlet end and an outlet end, the inlet end of the conduit being connected in fluidtight relationship to the outlet of the check valve assembly, the outlet end of the conduit being connectable in fluidtight relationship to the outer apertures of the metal disk via a spring-biased seal member carried by the rotor and slidably engageable in fluidtight relationship with the metal disk as the rotor member is rotated, the seal member being forced by spring-biasing against that side of the disk adjacent the rotor member;
• a cap member fastened to the valve body and generally covering the rotor and the metal disk, the cap member journaling the rotor for rotation, the position of the cap member on the body determining the position of the rotor axis of rotation relative to the flat metal disk, the cap member constituting the sole means for journaling and rotationally supporting the rotor;
• a push rod member having an exposed end portion extending through the cap, the push rod member sliding axially along the axis of rotation of the rotor member to open the check valve assembly;
• and
• a handle for rotating the rotor member and moving the push rod to open the check valve and thus provide fluid communication between the inlet port and a selected outlet port dependent on the position of the rotor member.
