Abstract
A low volume inlet reciprocating compressor suitable for use in a dual evaporator refrigeration cycle. The compressor includes a cylinder having an inlet port and an outlet port disposed in a housing. A flexible conduit having an inlet passage formed therein extends between the inlet port and an inlet in the housing, and a check valve is connected to the inlet passage so as to prevent refrigerant flow out of the conduit. The inlet passage is located as close as possible to the inlet port. A suction muffler can be located in the housing with one end connected to a second inlet in the housing and another end connected to the check valve. A discharge tube is provided between the outlet port and outlet opening in the housing.
Claims19
A reciprocating compressor comprising:
- a housing having a cylinder block disposed therein;
- a cylinder disposed within said cylinder block having an inlet port and an outlet port;
- a reciprocating piston disposed within said cylinder;
- a first conduit having an inlet passage, said first conduit extending between said inlet port and a first inlet of said compressor;
- a check valve connected to said inlet passage;
- a second conduit extending between said check valve and a second inlet of said compressor;
- and
- said check valve arranged so as to prevent flow from said first conduit to said second conduit but to permit flow from said second conduit to said first conduit if the pressure of said second conduit exceeds the pressure of said first conduit.
In a refrigeration system having a first evaporator, a second evaporator and an active valve connected to receive a portion of the refrigerant discharged from said first evaporator, a reciprocating compressor comprising:
- a housing having a first inlet connected to said active valve and a second inlet connected to said second evaporator;
- a cylinder block disposed in said housing and having a cylinder formed therein, said cylinder having an inlet port and an outlet port;
- a conduit extending between said inlet port and said first inlet and having an inlet passage formed therein;
- and
- a check valve connected to said inlet passage so as to prevent flow out of said conduit.
A refrigeration system comprising:
- a condenser;
- a first evaporator connected to receive at least a portion of the refrigerant discharged from said condenser;
- a second evaporator connected to receive a portion of the refrigerant discharged from said first evaporator;
- an active valve connected to receive a portion of the refrigerant discharged from said first evaporator;
- and
- a reciprocating compressor comprising a housing having a first inlet connected to said active valve and a second inlet connected to said second evaporator, a cylinder block disposed in said housing and having a cylinder formed therein, said cylinder having an inlet port and an outlet port, a conduit extending between said inlet port and said first inlet and having an inlet passage formed therein, and a check valve connected to said inlet passage so as to prevent flow out of said conduit.
