Clock mechanism flow regulator

An automatic injection device, comprising:

• a drug container which contains a pharmaceutical product, the drug container including a plunger;
• a fluid path which connects the drug container to an insertion device;
• an outer magnet and an inner magnet, the outer magnet located on an exterior portion of the drug container and the inner magnet located within the drug container;
• a spring surrounding the exterior portion of the drug container and connected to an outer collar comprising the outer magnet, wherein extension and retraction of the spring causes a linear movement of the outer magnet and the linear movement of the outer magnet causes corresponding movement of the inner magnet, and the inner magnet moves the plunger and forces the pharmaceutical product into the fluid path;
• and
• a regulator comprising:
• a clock escapement mechanism comprising at least one set of gears, and
• a linear translator comprising a rack and a pinion;
• wherein the linear translator is configured to convert a rotational movement of the at least one set of gears and the pinion into a linear motion of the rack,
• the clock escapement mechanism applies a counterforce to the spring to restrict release of potential energy from the spring over a proscribed period of time, and
• the at least one set of gears is configured to move upon movement of the spring.
