at an angle from the vertical, horizontal double-acting cylinders are also
arranged on each side, all operated from a single crankpin (Figure H).
Duplex reciprocating compressors are machines with cylinders mounted
on two parallel frames connected through a common crankshaft (Figure I).
Duplex Four-Cornered Steam-Driven reciprocating compressors are of
the duplex type and have steam and compressor cylinders on opposite
ends of each frame (Figure J).
Four-Cornered Motor-Driven reciprocating compressors are of the
duplex type with one or more compressing cylinders on each end of each
frame. The driving motor is mounted on the shaft between the frames
(Figure L).
Angle or L-type Integral gas or oil-driven compressors have the power
cylinders in a vertical or vertical-V arrangement and the compressing
cylinders in a horizontal plane (Figure M).
Horizontal Opposed reciprocating compressors are multi-cylinder
machines on opposite sides of the crankcase; they employ a multi-throw
type of shaft with one crank throw per cylinder. Power is applied at the
end of the shaft (Figure N).
