A compressor is disclosed generally comprising a cylinder head mounted to a cylinder block having a cooling chamber and a piston channel via a bolt. A piston is disposed in the piston channel and has a contact portion that contacts the channel wall, which is integrally formed with the cylinder block, as it slides within the channel. The bolt and the cooling chamber each extend from at least as high as the highest contact point between the contact portion of the piston and the channel wall to at least as low as the lowest contact point between the contact portion of the piston and the channel wall. In certain embodiments, the cooling chamber is located between the bolt and the piston channel. In some embodiments, a crankcase is integrally formed with the cylinder block.
