  • Sealed refrigeration system and appliance
    Patent number: 10281170
    Abstract: A sealed refrigeration system and appliance are provided. The sealed refrigeration system may include a compressor, a condenser, an evaporator, and a check valve assembly. The compressor may be operable to compress refrigerant, while the condenser may be disposed in downstream fluid communication with the compressor to condense refrigerant received from the compressor. The evaporator may be disposed in fluid communication between the condenser and the compressor. The check valve assembly may be disposed in fluid communication between at least two components of the sealed refrigeration system. The check valve assembly may include a valve body defining a circuit inlet, a circuit outlet, and a charge port. The circuit outlet may be downstream from the circuit inlet to direct refrigerant therefrom. The charge port may be between the circuit inlet and the circuit outlet to receive refrigerant therethrough.
