Abstract
A compressor includes a first piston, a second piston, and a crank. A first case chamber is defined by a lower surface of a first piston head, a portion of a first cylinder surface disposed below the lower surface of the first piston head, and a first case surface. A second case chamber is defined by a lower surface of a second piston head, a portion of a second cylinder surface disposed below the lower surface of the second piston head, and a second case surface. The first case chamber and the second case chamber are fluidly isolated from one another. The crank is to reciprocate the first piston head and the second piston head up and down.

A compressor comprising:
- a first piston having a first piston head, a first cylinder surface, a first case surface, a first piston chamber, and a first case chamber, the first case chamber being defined by a lower surface of the first piston head, a portion of the first cylinder surface disposed below the lower surface of the first piston head, and the first case surface;
- a second piston having a second piston head, a second cylinder surface, a second case surface, a second piston chamber, and a second case chamber, the second case chamber being defined by a lower surface of the second piston head, a portion of the second cylinder surface disposed below the lower surface of the second piston head, and the second case surface, wherein the first case chamber and the second case chamber are fluidly isolated from one another;
- and
- a crank to reciprocate the first piston head and the second piston head up and down.
A refrigerant recovery unit, comprising:
- a service coupler configured to convey a refrigerant to a refrigeration system;
- and
- a compressor comprising:
- a first piston having a first piston head, a first cylinder surface, a first case surface, a first piston chamber, and a first case chamber, the first case chamber being defined by a lower surface of the first piston head, a portion of the first cylinder surface disposed below the lower surface of the first piston head, and the first case surface;
- a second piston having a second piston head, a second cylinder surface, a second case surface, a second piston chamber, and a second case chamber, the second case chamber being defined by a lower surface of the second piston head, a portion of the second cylinder surface disposed below the lower surface of the second piston head, and the second case surface, wherein the first case chamber and the second case chamber are fluidly isolated from one another;
- and
- a crank to reciprocate the first piston head and the second piston head up and down.
A method of compressing a refrigerant comprising the steps of:
- compressing the refrigerant with a first piston having a first piston head, a first cylinder surface, a first case surface, a first piston chamber, and a first case chamber, the first case chamber being defined by a lower surface of the first piston head, a portion of the first cylinder surface disposed below the lower surface of the first piston head, and the first case surface;
- compressing the refrigerant with a second piston having a second piston head, a second cylinder surface, a second case surface, a second piston chamber, and a second case chamber, the second case chamber being defined by a lower surface of the second piston head, a portion of the second cylinder surface disposed below the lower surface of the second piston head, and the second case surface, wherein the first case chamber and the second case chamber are fluidly isolated from one another;
- and
- reciprocating the first piston head and the second piston head up and down with a crank.
