Run selector apparatus and run selector biasing system

A run selector system comprising:

• a housing having an input port and first and second output ports;
• a valve member disposed in the housing, the valve body member comprising a valve body member moveable between opposite first and second run selection positions relative to the housing, the valve body member in the first run selection position relative to the housing defining a first fluid circuit comprising the input port opened to the first output port and closed to the second output port, and the valve body member in the second run selection position relative to the housing defining a second fluid circuit comprising the input port closed to the first output port and opened to the second output port;
• an interface device;
• and
• a control arm member operatively coupled with the valve body member by the interface device for moving the valve body member between the first and second run selection positions relative to the housing, the control arm member being movable between opposite first and second control arm positions corresponding respectively to the first and second run selection positions of the valve body member,
• wherein the interface device comprises:
• a first interface element on the valve body member;
• a second interface element on the control arm member;
• and
• a resilient member disposed between the first and second interface elements, the resilient member being compressible between the first and second interface elements to permit limited relative movement between the control arm member and the valve body member.

A run selector device self-compensated for obstructions, comprising:

• a valve housing comprising a housing body defining:
• an input port for conducting an input fluid flow into the housing body;
• a first output port in fluid communication with the input port for conducting the input fluid flow out of the housing as a first output fluid flow;
• a second output port in fluid communication with the input port for conducting the input fluid flow out of the housing as a second output fluid flow;
• a valve disposed in the housing, the valve defining a valve body member having:
• a proximal end pivotable about a pivot axis between opposite first and second positions for porting the input fluid flow to the first and second output ports, respectively, of the housing body;
• and
• a distal end sealing the valve body against opposite first and second surfaces of the housing body for the valve body being disposed in the opposite first and second positions, respectively,
• wherein the distal end of the valve body comprises a flexible portion extending along an edge of the valve body.
