EXTENDED TRAVEL FLEXURE BEARING AND MICRO CHECK VALVE

摘要

Variations of the devices and methods disclosed herein pertain to an extended travel spiral flexure bearing having spiral arms, each of the spiral arms including an attachment point at the inner end thereof and at the outer end thereof. Variations of the bearing may also include a bearing clamp to be attached to the spiral flexure bearing at the attachment points, the bearing including an outer bearing portion to be disposed on the outer periphery of the flexure bearing and an inner bearing portion to be disposed at the center of the flexure bearing. Variations also pertain to a micro check valve assembly that includes a valve base, a valve cover, and a flexure that are all bonded together. The valve being closed when the valve door rests on the valve seat and open when the valve door is lifted from the valve seat.

主权项

1. An integrated detector cooler assembly (IDCA) comprising:
a cryostat having at least one cooling circuit disposed therein; a compressor; and a refrigerant source having a refrigerant to be provided to the cooling circuit; where the compressor provides the refrigerant to the cooling circuit, the cooling circuit being configured for closed-loop operation; and the compressor includes a compressor pump, the compressor pump including a piston operably connected to an extended travel spiral flexure bearing, the extended travel spiral flexure bearing having two or more spiral arms arranged in a spiral pattern originating at a center of the bearing and extending outward towards an edge of the bearing, being configured for unlimited fatigue life and further, being configured to enable lateral movement of the piston in a plane perpendicular to a plane of the extended travel spiral flexure bearing.
