Motorized control valves

Claim 2

A MOTORIZED CONTROL VALVE ASSEMBLY, COMPRISING: AN ELECTRIC MOTOR INCLUDING AN OUTPUT SHAFT; BRACKET MEANS HAVING A BASE AND A PAIR OF SPACED WALLS EXTENDING FROM SAID BASE; MEANS MOUNTING SAID MOTOR UPON ONE OF SAID WALLS; A PRESSURE-RESPONSIVE VALVE, INCLUDING: A HOUSING; FLOW CONTROL MEANS IN SAID HOUSING; ADJUSTABLE BIASING MEANS IN SAID HOUSING ARRANGED TO EXERT FORCE ON SAID FLOW CONTROL MEANS TO ESTABLISH THE PRESSURE TO WHICH SAID VALVE WILL RESPOND; AND A ROTATABLE ADJUSTING MEMBER CARRIED BY SAID HOUSING AND OPERABLE UPON ROTATION THEREOF TO ADJUST THE FORCE EXERTED BY SAID BIASING MEANS TO THEREBY VARY THE PRESSURE TO WHICH SAID VALVE WILL RESPOND, SAID ADJUSTING MEMBER INCLUDING A PORTION ENGAGEABLE FROM THE EXTERIOR OF SAID HOUSING; MEANS MOUNTING SAID VALVE ON THE OTHER WALL OF SAID BRACKET MEANS, WITH SAID OUTPUT SHAFT ALIGNED WITH SAID ADJUSTING MEMBER; AND MEANS DIRECTLY INTERCONNECTING SAID MOTOR SHAFT AND SAID ENGAGEABLE PORTION OF SAID ADJUSTING MEMBER, WHEREBY THE ADJUSTING MEMBER CAN BE ACTUATED BY ENERGIZING SAID MOTOR.

Claim 3

IN COMBINATION: A MAIN VALVE HAVING AN INLET, AN OUTLET, AND FLUID PRESSURE OPERABLE MEANS CONTROLLING THE FLOW OF FLUID FROM SAID INLET TO SAID OUTLET; AND A MOTORIZED CONTROL FOR SAID MAIN VALVE INCLUDING: A PRESSURERESPONSIVE PILOT VALVE CONNECTED WITH SAID MAIN VALVE FOR CONTROLLING THE APPLICATION OF OPERATING FLUID TO SAID FLUID PRESSURE OPERABLE MEANS TO MAINTAIN A GIVEN OPERATING FUNCTION OF SAID MAIN VALVE, SAID PILOT VALVE INCLUDING: A HOUSING; FLOW CONTROL MEANS WITHIN SAID HOUSING; ADJUSTABLE BIASING MEANS IN SAID HOUSING ARRANGED TO EXERT FORCE ON SAID FLOW CONTROL MEANS TO ESTABLISH THE PRESSURE TO WHICH SAID PILOT VALVE WILL RESPOND; AND AN ADJUSTING SCREW CARRIED BY SAID HOUSING AND OPERABLE UPON ROTATION THEREOF TO ADJUST THE FORCE EXERTED BY SAID BIASING MEANS TO THEREBY VARY THE PRESSURE TO WHICH SAID PILOT VALVE WILL RESPOND, SAID ADJUSTING SCREW INCLUDING A PORTION ENGAGEABLE FROM THE EXTERIOR OF SAID HOUSING; AN ELECTRICAL MOTOR INCLUDING A LOW SPEECH OUTPUT SHAFT; BRACKET MEANS CONNECTING TOGETHER SAID PILOT VALVE AND MOTOR, WITH SAID SHAFT IN AXIAL ALIGNMENT WITH SAID ADJUSTING SCREW; AND MEANS CONNECTING SAID SHAFT DIRECTLY TO SAID ENGAGEABLE PORTION OF SAID ADJUSTING SCREW FOR CHANGING THE ADJUSTMENT THEREOF UPON ENERGIZATION OF SAID MOTOR.

Claim 4

IN COMBINATION: A MAIN VALVE HAVING AN INLET, AN OUTLET, AND FLUID PRESSURE OPERABLE MEANS CONTROLLING THE FLOW OF FLUID FROM SAID INLET TO SAID OUTLET; AND A MOTORIZED CONTROL FOR SAID MAIN VALVE INCLUDING: A PRESSURERESPONSIVE PILOT VALVE CONNECTED WITH SAID MAIN VALVE FOR CONTROLLING THE APPLICATION OF OPERATING FLUID TO SAID FLUID PRESSURE OPERABLE MEANS TO MAINTAIN A GIVEN OPERATING FUNCTION OF SAID MAIN VALVE, SAID PILOT VALVE INCLUDING: A HOUSING; FLOW CONTROL MEANS WITHIN SAID HOUSING; ADJUSTABLE BIASING MEANS IN SAID HOUSING ARRANGED TO EXERT FORCE ON SAID FLOW CONTROL MEANS TO ESTABLISH THE PRESSURE TO WHICH SAID PILOT VALVE WILL RESPOND; AND AN ADJUSTING SCREW CARRIED BY SAID HOUSING AND OPERABLE UPON ROTATION THEREOF TO ADJUST THE FORCE EXERTED BY SAID BIASING MEANS TO THEREBY VARY THE PRESSURE TO WHICH SAID PILOT VALVE WILL RESPOND, SAID ADJUSTING SCREW INCLUDING A PORTION ENGAGEABLE FROM THE EXTERIOR OF SAID HOUSING; AN ELECTRICAL MOTOR INCLUDING A LOW SPEECH OUTPUT SHAFT; BRACKET MEANS CONNECTING TOGETHER SAID PILOT VALVE AND MOTOR, WITH SAID SHAFT IN AXIAL ALIGNMENT WITH SAID ADJUSTING SCREW; AND MEANS CONNECTING SAID SHAFT DIRECTLY TO SAID ENGAGEABLE PORTION OF SAID ADJUSTING SCREW FOR CHANGING THE ADJUSTMENT THEREOF UPON ENERGIZATION OF SAID MOTOR.
