High force booster actuator

A booster actuator for a fire suppression system, comprising:

• a body;
• an input shaft received by the body and configured to receive an input force;
• a spring received by the body and configured to move from a loaded position to an unloaded position to provide a spring force based on the input shaft receiving the input force;
• an output shaft received by the body and configured to receive the spring force and provide an output force greater than the input force;
• and
• a cam assembly coupled with the body and configured to retain the spring in the loaded position until the input force is received by the input shaft.

A booster actuator for a fire suppression system, comprising:

• a body comprising:
• a first end defining a first aperture;
• and
• a second end opposite the first end, the second end defining a second aperture;
• an actuation pin configured to translate within the first aperture between a first position and a second position, the actuation pin defining a first recessed surface;
• at least one cam assembly, the cam assembly comprising:
• a cam rotatably coupled with the body;
• a first bearing located on a first end of the cam, the first bearing configured to engage the first recessed surface when the actuation pin is in a second position;
• and
• a second bearing located on a second end of the cam opposite the first end of the cam;
• an actuation spring housed within the body, wherein the actuation spring is preloaded;
• and
• an actuation shaft configured to translate within the second aperture, the actuation shaft including a second recessed surface configured to engage the second bearing while the actuation pin is in the first position;
• wherein as the actuation pin moves from the first position to the second position, the cam rotates such that the first bearing engages the first recessed surface and the second bearing disengages from the second recessed surface to enable the actuation shaft to move to an actuated position.
