The present invention provides a fluid controlling apparatus that has a remote signal transmitter that sends a signal to a signal receiver that has power supplied to it by a power supply. The signal receiver now generates a new signal to a valve controller which controls a solenoid operated valve that controls fluid flow from an inlet to an outlet. A first embodiment controls fluid flow which shuts down a power take off commonly driven by an internal combustion engine while a second embodiment controls fluid flow to shut down by movement of an intake air blocker valve, an internal combustion engine. Both embodiments include an indicator including a standby indicating light and an operational indicating light. The valve controller in the first embodiment includes a main solenoid with a fluid flow operated grounding switch for permitting operation of the solenoid operated valve that controls the fluid flow from the inlet to the outlet.
In a fluid flow controlling apparatus for controlling the flow of pressurized fluid comprising in combination, a remote signal transmitting means, a signal receiving means adapted to receive a signal from said signal transmitting means, a fluid inlet means, a solenoid operated shut off valve and a fluid outlet means all in series, control means for controlling the operation of said solenoid operated shut off valve upon receipt of a signal generated from said signal receiving means upon receipt of said signal from said signal transmitting means, power supply means, said control means including a main solenoid means activated by said generated signal to transfer power from said power supply means to said solenoid operated shut off valve thereby preventing fluid from flowing from said fluid inlet means to said fluid outlet means and wherein said main solenoid means includes a power supply inlet post for receiving power from said power supply means, a power supply outlet post for transferring power to said shut off valve solenoid, a main solenoid activate post for receiving said generated signal and a main solenoid ground return circuit post and further including a jumper means between said main solenoid activate post and said power supply outlet post for ensuring continued power to said shut off valve solenoid upon cessation of said generated signal.
A fluid flow controlling apparatus for controlling flow of pressurized fluid comprising in combination, a solenoid operated safety valve biased in the closed position when unactivated, a solenoid operated shut off valve biased in the open position when unactivated, an inlet for said pressurized fluid, an outlet for said pressurized fluid, said solenoid operated shut off valve and said solenoid operated safety valve being in series between said inlet and said outlet, control means for controlling said solenoid operated shut off valve, transmitter means, receiver means for receiving a signal from said transmitter means to activate said control means to control said solenoid operated shut off valve, power supply means, said solenoid operated safety valve being controlled by activating said power supply means, switch means operated by said fluid pressure presence for making effective said solenoid operated shut off valve control means, whereby said pressurized fluid entering said fluid flow controlling apparatus operates said switch means, passes through said biased open solenoid operated shut off valve and said power supply means being connected to said solenoid operated safety valve opens said biased closed solenoid operated safety valve to let the pressurized fluid exit.
A pressurized fluid flow controlling apparatus comprising in combination, a grounded electrical power supply means, including ground return circuits, remote signal transmitting means, signal receiving means powered by said power supply means and adapted to be actuated by a signal transmitted from said remote signal transmitting means, valve means, valve control means for controlling a first portion of said valve means and powered by said grounded electrical power supply means, said valve control means including a control signal generated by said signal receiving means, whereby fluid entering said fluid flow controlling apparatus is controlled at will by actuating said remote signal transmitting means and wherein said ground return circuits include a switch connected to said valve control means and operated by said fluid pressure entering said apparatus to connect a portion of said ground return circuits to said grounded electrical power supply means to permit controlled operation of said first portion of said valve means.
