The present application includes a compressor having a cylinder forming a compression chamber in which gas is compressed, a housing having a peripheral wall forming an internal space in which the compressor is stored, and a supporting member situated above the compressor in the internal space. The peripheral wall includes an opening wall in which a carry-out port is formed through which the cylinder is carried out. The supporting member extends to guide movement of a first lifting device between a position above the compressor and a position above the carry-out port. The cylinder is hung from the first lifting device.

A corner drive assembly for a window locking system includes a case, a corner transfer spring, and first and second arms. The case includes first and second legs aligned with respective first and second axes. The legs are joined by a corner portion having an outer relief surface that is disposed adjacent to and spaced apart from a corner of a window frame. The spring is slidably disposed within the corner portion and has first and second ends slidable along the first and second axes, respectively. The first arm is disposed within the first leg, slidable along the first axis, and coupled to the first end of the spring. The second arm is within the second leg, slidable along the second axis, and coupled to the second end of the spring. The first and second arms are coupled to respective first and second link bars of the locking system.
