Abstract
An electro-magnetic thermal control valve (EMTCV) is configured to selectably direct and control an amount of coolant fluid to a cooler in a coolant circulation system. The EMTCV includes a valve housing defining a main chamber, an electromagnet disposed in the valve housing, and a movable sleeve disposed within the main chamber. The movable sleeve is fixedly attached to a permanent magnet adjacent to the electromagnet. When the electromagnet is energized by a current supplied by a valve control system, the electromagnet exerts a force on the permanent magnet, moving the movable sleeve is from an idle position to plurality of intermediate positions or an actuated position.
Claims20
A coolant circulation system for regulating a discharge temperature in a compressor airend, the coolant circulation system comprising:
- a cooler configured to cool a coolant fluid circulating through the coolant circulation system;
- and
- an electro-magnetic thermal control valve (EMTCV) configured to direct and control the amount of coolant fluid to the cooler, the EMTCV including:
- a valve housing defining a main chamber, a coolant fluid inlet, a coolant fluid outlet, a cooler inlet, and a cooler outlet,
- a valve endcap removably attached to the valve housing, the valve endcap covering an opening to the main chamber,
- an electromagnet disposed in the valve endcap,
- a movable sleeve disposed within the main chamber, the movable sleeve having a first end, the first end of the movable sleeve holding a permanent magnet, and
- an end plate disposed on the valve housing proximate to the valve endcap, the end plate configured to hold the permanent magnet within the main chamber,
- the movable sleeve configured to move between an idle position, an intermediate position, and an actuated position, wherein when the electromagnet is energized the electromagnet exerts a force with respect to the permanent magnet, to move the movable sleeve towards the actuated position.
