Abstract
A mechanical actuator assembly is disclosed. The actuator assembly comprises an actuator body with an element moveable with respect to said body to perform a function. In general, the moveable element is in the form of a piston or a rod. The actuator assembly further comprises a mounting mechanism allowing the movement of the actuator body relative to the moving element or piston in response to preset conditions of pressure or force.
Claims6
An actuator comprising:
- a body;
- an element movable with respect to said body to perform a function;
- and
- a mounting mechanism allowing the movement of the body relative to the moving element in response to preset conditions;
- wherein the actuator is selected from the group consisting of:
- high output force mechanical, pneumatic, hydraulic, and thermochemical actuators;
- and
- wherein the mounting mechanism comprises a linear slide spring loaded into a stop and attached to the body of the actuator wherein the slide retracts when output force exceeds spring preload.
5 more elements
A thermal actuator comprising:
- a body comprising a chamber filled with a medium that expands and contracts in response to thermal conditions;
- a piston slidably received in the chamber for extending as the medium expands generating an output force;
- and
- a mounting mechanism for attaching the actuator to a larger device comprising a linear slide spring-loaded into a stop and attached to the body of actuator wherein the slide retracts when output force exceeds spring preload.
1 more element
A mounting mechanism for attaching an actuator to a mechanical structure comprising,
- a plate to retain the actuator in its position,
- a linear slide attached to the actuator,
- a spring with a preset load value attached to the slide, and
- a mounting bracket,
- wherein the linear slide moves the actuator away from the mechanical structure when the actuator force exceeds the preset load value of the spring.
