Valve assembly failsafe

A valve assembly failsafe configured to be coupled to an actuator of a coolant control regulator assembly, the valve assembly failsafe comprising:

• a housing comprising a reset aperture;
• an electrical connector linked to the housing;
• a spring positioned within the housing;
• a wind arm that engages the spring and comprises a reset interface;
• a latch that engages the wind arm;
• a driver that engages the latch;
• and
• a drive gear configured to engage the actuator of the coolant control regulator assembly,
• wherein the valve assembly failsafe is configured to be transitioned from a set state in which the wind arm and the spring are under spring tension, to a tripped state in which the spring is unloaded such that the wind arm engages and rotates the drive gear,
• wherein the valve assembly failsafe is configured to be transitioned from the tripped state back to the set state, and
• wherein the reset interface of the wind arm is positioned within the reset aperture.

A coolant control regulator assembly, comprising:

• a housing;
• an actuator coupled to the housing and having a hard-stop;
• a plurality of ports extending from the housing;
• a plurality of ball valves positioned within the housing, each ball valve connected to one or more of the ports;
• and
• a valve assembly failsafe mounted on the actuator and comprising:
• a spring configured to be under spring tension;
• a wind arm that engages the spring;
• a latch that engages the wind arm;
• a driver that engages the latch;
• and
• a drive gear configured to engage the actuator of the coolant control regulator assembly,
• wherein the valve assembly fail safe is configured to be positioned in a state selected from the group of states consisting of:
• a set state, wherein the latch engages and retains the wind arm, the wind arm does not engage the drive gear, and the drive gear freely rotates during rotation of the actuator, and
• a tripped state, wherein the wind arm is disengaged from the latch and engages the drive gear,
• wherein the hard stop is configured to hold the actuator in a default position, and
• wherein the spring tension is sufficient to cause the drive gear to drive the actuator to the default position, when the valve assembly failsafe is in the tripped state.
