    Abstract: The gas compression/expansion apparatus comprises: a working section for compressing/expanding therein a working gas by pistons each connected with a rod; a drive section including sliders each connected at one end thereof with the rod and connected at one end thereof with a guide for guiding the slider, and a drive mechanism for reciprocating the sliders; and a separator for fluid dynamically separating the working section from the drive section, the separator permitting said rod to pass through said separator. The separator further includes an oil seal arrangement. Formed inside the separator is an intermediate chamber which allows the rod to pass there through. The inner radius of the intermediate chamber is greater than the radius of the rod plus the oil deposited on the rod. The guide includes a guide space formed such that the distance between the slider at its upper dead point and the wall of the separator facing the slider is larger than the thickness of the oil on the slider. The separator also includes an oil return passage for allowing the oil accumulated in the guide space to return to an oil sump. The oil seal arrangement may prevent the oil on the guide from coming into direct contact with the separator and prevent the oil on the rod from entering the working section.

    Abstract: The annular seal assembly and seal arrangements including the seal assembly disclosed are useful in high pressure pumps and compressors and the like that include a cylinder having annular grooves therein for receiving the seal arrangements and having a plunger reciprocating in the cylinder through the seal arrangements. The seal assembly includes segmented tangent and radial ring assemblies. Each of the segments in the tangent ring assembly includes tangentially disposed end surfaces that are arranged to sealingly and slidingly engage the adjacent tangentially disposed end surfaces. The radial ring assembly is constructed from a plurality of arcuate segments having an outer periphery sized to be closely fitted into a counterbore formed in one face of the tangent ring assembly. With the radial and tangential rings assembled, the forces exerted by the high pressure fluid on the tangent ring assembly are transferred to the radial ring assembly, providing better lubrication and longer seal life. The disclosed seal arrangements promote better operation and better seal life due to the distribution of the pressure load over several seals.

    Abstract: The improved packing rings described in detail hereinafter provide an integrally formed, internally located check valve for use in the lubrication systems compressors, pumps or the like. Specifically, and in the preferred form, two adjacent packing rings include face portions arranged in sealing engagement with at least one of the packing rings a lubricant passageway therein. An arcuate groove is formed in the face of one of the packing rings in communication with the lubricant passageway. One of the packing rings includes a pressure-responsive, integrally formed annular lip that encompasses the arcuate groove. The arrangement is such that a predetermined pressure in the lubricant groove moves the lip away from the adjacent packing ring permitting lubricant to pass out of the arcuate groove into the interior of the compressor. During the compression stroke of the compressor, the high pressure existing inside the compressor acts on the pressure responsive lip forcing it into tighter sealing engagement with the adjacent packing ring preventing the compressor pressure from entering the lubrication system.
