Abstract
A linear type of compressor wherein a housing section, for enclosing a crankshaft and pinions of a counterbalancing synchronizer, has axially extending support means for the pinions formed integrally therewith through an inner flange also integral with the housing section, so that the holes for the pinion shafts may be formed in the support means when the hole in the housing for the crankshaft is formed. This assures the making of all of the holes exactly parallel and avoids time-consuming assembly work, experienced in prior art compressor manufacturing, when the housing sections are put together. By providing a large opening through the upper portion of the support means or through the bottom of the housing an axial bore may be made to receive a piston type of crosshead. By cutting down on the number of compressor parts and the manufacturing tolerances involved in the manufacture of the parts and the use of U-shaped members as guides for gear racks and as retainers for the pinion shafts, a further saving in manufacturing cost is obtained.
