Abstract
A booster actuator 10 may be positioned between the solenoid 12 and a valve 14, and increases the energy output from the solenoid to activate the valve. The booster actuator 10 may include a force input member 28 and a force output member 30 each linearly movable with respect to a body 20 from an initial position to an activated position. A coil spring 46 biases the input member to the initial input position, while a plurality of disk springs 48 bias the output member 30 to the activated output position. A plurality of linking members 32 each pivotable with respect to the body normally retain the force output member in the initial position, but upon movement of the input member to the activated position release the force output member in response to the disk springs.
Claims25
An actuator for receiving an energy input and outputting an energy output, the actuator comprising:
- a body having a force receiving input end and force delivery output end;
- a force input member movable relative to the body in direct response to the energy input from an initial input position to an activated input position;
- a force output member movable relative to the body in response to movement of the force input member from an initial output position to an activated output position, the energy output being independent with respect to the energy input;
- a first biasing member means for biasing the force input member to the initial input position, wherein the energy input overcomes the first biasing member means to move the force input member from the initial input position to the activated input position;
- a second biasing member for biasing the force output member;
- and
- a linking member between the force input member and the force output member and pivotally movable with respect to the body from an engaged position for retaining the force output member in the initial output position to a disengaged position for releasing the force output member to the activated output position, the linking member having an input end engaging the force input member and an output end engaging the force output member.
An actuator for receiving an energy input and outputting an energy output, the actuator comprising:
- a body having a force receiving input end and force delivery output end;
- a force input member linearly movable relative to the body in direct response to the energy input from an initial input position to an activated input position;
- a first biasing member means for biasing the force input member, wherein the energy input overcomes the first biasing member means to move the force input member to the activated input position;
- a force output member linearly movable relative to the body in response to movement of the force input member from an initial output position to an activated output position, the energy output being independent with respect to the energy input;
- a second biasing member for biasing the force output member;
- and
- a linking member between the force input member and the force output member and movable from an engaged position for retaining the force output member in the initial output position to a disengaged position for releasing the force output member to the activated output position.
A booster actuator for receiving a low energy input and outputting a high energy output, the booster actuator comprising:
- a body having a force receiving input end and force delivery output end;
- a force input member movable relative to the body in direct response to the energy input from an initial input position to an activated input position;
- a first biasing member means for biasing the force input member, wherein the energy input overcomes the first biasing member means to move the force input member to the activated input position;
- a force output member movable relative to the body in response to movement of the force input member from an initial output position to an activated output position, the energy output being independent with respect to the energy input, resetting the force input member being dependent on resetting the force output member;
- a second biasing member for biasing the force output member;
- and
- a linking member between the force input member and the force output member;
- and pivotally movable with respect to the body from an engaged position for retaining the force output member in the initial output position to a disengaged position for releasing the force output member to the activated output position, the linking member having an input end engaging the force input member and an output end engaging the force output member.
An actuator for receiving an energy input and outputting an energy output, the actuator comprising:
- a body having a force receiving input end and force delivery output end;
- a force input member movable relative to the body in response to the energy input from an initial input position to an activated input position;
- a first biasing member for biasing the force input member;
- a force output member movable relative to the body in response to movement of the force input member from an initial output position to an activated output position;
- a second biasing member for biasing the force output member;
- and
- a linking member between the force input member and the force output member and movable from an engaged position for retaining the force output member in the initial output position to a disengaged position for releasing the force output member to the activated output position,
- wherein resetting the force output member from the activated output position to the initial output position moves the linking member to the engaged position and increases force on the first biasing member to return the force input member to the initial input position.
