Patent CA-1308403-C (CA)
Title: Scroll type compressor
Inventor: OCHIAI YOSHIHIRO
IPC: F04C18/02
Filed: 1988-04-05
Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE      A scroll type compressor includes a housing having an inner chamber and fluid inlet and outlet ports connected to the inner cham-ber. A fixed scroll is mounted within the housing and has a circular end plate from which a first spiral element extends. An orbiting scroll is also mounted within the housing for orbital motion with respect to the fixed scroll, and includes a circular end plate from which a second spiral element extends. The fixed scroll and the orbiting scroll are maintained angularly and radially offset from each other so that the spiral elements interfit to form a plurality of line contacts between their spiral curved surfaces which seal-off and define at least one pair of fluid pockets. The orbital movement of the orbiting scroll relative to the fixed scroll shifts the line contacts along the spiral curved surfaces of the spiral elements which changes the volume of the fluid pockets. The end plate of the fixed scroll partitions the inner chamber of the housing into a suction chamber and a discharge chamber. A sealing structure is disposed between the inner peripheral wall of the housing and the outer peripheral surface of the end plate of the fixed scroll. The sealing structure includes an annular cut-out portion, having an L-shaped sectional side view, formed in the outer peripheral surface of the end plate of the fixed scroll, an annular ridge formed in the inner peripheral wall of the housing and an O-ring seal element disposed between the annular cut-out portion and the annular ridge.

Title: Tensioning and recoil system for a tracked vehicle
Inventor: TONSOR ANDREW J
IPC: B62D55/30
Filed: 1989-07-10
Granted: 1992-08-18
Abstract: Abstract of the Disclosure Tensioning and Recoil System For a Tracked Vehicle A tensioning and recoil system establishes and maintains a substantially constant force on an idler wheel of an endless track assembly for a tracked vehicle.  The force applied to the idler wheel tensions the endless track and maintains a predetermined frictional force between the track and a powered drive wheel.  The system also provides a recoil function for the idler wheel during ingestion of foreign material between the track and the idler and drive wheels.  The tensioning and recoil system includes a recoil tube which telescopes into a cylinder and a single sealed and closed chamber filled with a compressible gas.  Conventional recoil systems for self-laying track-type vehicle utilize pre-compressed large diameter steel coil springs to resist recoiling during light loading of the idler wheel and to return the wheel to the normal position after recoiling during heavy loading.  These coil springs are quite heavy and bulky, require considerable space, and must be maintained in a pre-compressed state under large forces.  This requires extremely strong retaining devices and special assembly and disassembly procedures.  The subject tensioning and recoil system incorporates a compressible gas spring in place of the large coil steel spring, thereby requiring less space, less weight, and simplified assembly and disassembly.  The subject system establishes and maintains a constant force on the idler wheel and the endless track and responds immediately to recoil situations.
