Abstract: Downsizing a piston stroke dimension in a compressor that reciprocates pistons is accomplished by changing a radial directional component of a shaft of a motion that is transferred to a link from a revolving member revolved by the shaft when transferred to the link attached to the pistons. Thereby, when the revolving member, driven by a shaft, revolves once, a center of a sliding pin appears to reciprocate once in a vertical direction as it goes back and forth on both sides interposing a piston axial line. Thus, when the revolving member revolves once, the piston reciprocates twice in a cylinder bore in a direction parallel to the longitudinal direction of the driving shaft.

By choosing an appropriate value for this offset distance, a characteristic curve of piston top clearance relative to change of oblique angle of the swash plate remains at a value of about zero over a relevant range of the oblique angle of the swash plate. As a result, volumetric efficiency of the compressor is effectively improved.

Abstract: In hydraulically actuated fuel injectors that utilize lubricating oil as the actuation fluid, various components within the injector body must move relatively short distances at high rates of speed in a wetted oil environment. When the oil is at a relatively low temperature, its relatively high viscosity coupled with relatively small size of these components can cause stiction problems to occur. Stiction occurs where the moveable component comes in contact with the body when it rests against its stop. The highly viscous oil can tend to cause the component to resist breaking free of its stop surface such that the fuel injector may be inhibited in performing adequately, especially during cold start conditions. These potential stiction problems are reduced by including a raised surface feature on one or both of the component and body in order to reduce the potential contact surface area.

First and second covers are located at opposite axial ends of the filter cartridge for sealing the system. At least one biasing assembly is disposed at one axial end of the filter cartridge for applying an approximately constant compression force to the filter medium. The compression force minimizes the formation of voids and the occurrence of bridging within the filtering media. A sensing mechanism, such as a Hall Effect sensor, can be applied to the filter cartridge for detecting changes in the filtering media which indicate the formation of voids or defects in the filtering media.
