Abstract: A locking handle for a refrigerator includes a mounting element rigidly secured to a refrigerator door, a hand grip rigidly secured to the mounting element, and a latch attached to the mounting element. The latch has a catch movable between a locked position and an unlocked position and an actuator operably connected to the catch for moving the catch from the locked position to the unlocked position. The latch provides a positive lock which is actuated to an unlocked position with a manipulation separate from pulling the hand grip but has an actuator located near the hand grip so that it can be manipulated by a hand grasping and pulling the hand grip. In a first embodiment, the catch is integrally molded with the mounting portion and is laterally deflectable away from a retainer mounted beside the door. In a second embodiment the catch is a vertically extending spindle which is downwardly movable away from a retainer mounted above the door.

Abstract: A vapor compression refrigeration system for cooling a cabinet having a thermostat for cycling the compressor off and on to maintain a predetermined temperature range in the cabinet includes a subcooling flow control valve at the inlet to the capillary tube restriction. The valve is operated by a sealed bellows containing a refrigerant so that the valve is responsive to the fluid entering the valve. The valve is calibrated so that only a subcooled liquid refrigerant can flow through the valve and if the entering refrigerant is above a predetermined level the valve will close to completely block all flow between the condenser and the evaporator, and the valve will stay in the closed position at all times when the compressor is not running.
