Abstract: A reciprocating compressor drive for driving a pair of opposed horizontally arranged compressor pistons. The pistons are carried by a pair of coaxial horizontal piston rods which are fixed to a crosshead situated between the piston rods and formed with a vertical slot receiving a slide block connected to a crank pin which is driven by a rotary crank drive. A pair of guide bars, which are parallel to the piston rods, extend through upper and lower bores of the crosshead, these bores carrying suitable bearings which slide along the guide bars. A pressurized lubricating system is provided for lubricating components such as the bearings which slide on the guide bars and the crank pin which is received in the slide block, the crosshead preferably being made of a light-weight material such as a plastic and carrying steel guide strips which slidably engage the slide block, the latter as well as the bearings which engage the guide bars preferably being made of bronze while the guide strips which engage the slide block and the guide bars which engage the bearings are preferably made of steel.
