    摘要： A system, in certain embodiments, includes a centrifugal compressor diffuser including a flow path having a first surface and a second surface defining opposite axial sides of the flow path. The centrifugal compressor diffuser also includes multiple vanes extending from the first surface to the second surface of the flow path. A first profile of each vane varies along an axial direction. The centrifugal compressor diffuser further includes multiple vanelets extending from the first surface toward the second surface in the axial direction. A first axial extent of each vanelet is less than a second axial extent of the flow path. In addition, a second profile of each vanelet varies along the axial direction and/or the vanelets form a non-periodic pattern around a circumference of the flow path.

    摘要： A system, in certain embodiments, includes a centrifugal compressor diffuser having a mounting surface and plurality of diffuser vanes extending from the mounting surface in an axial direction and forming an asymmetrical (e.g., non-periodic) pattern around the circumference of the diffuser. The asymmetrical pattern may be determined based upon characteristics of fluid flowing from an impeller across the diffuser and through a scroll of a centrifugal compressor.

    摘要： A cargo container attachment for a small vehicle such as a lawn tractor is provided. The container is removably attached to the rear of the vehicle and includes a cargo box storage space with a pivotally mounted swingable tailgate. The container is designed to be used in conjunction with a lawn tractor to perform landscaping and structural maintenance tasks. Materials such as mulch, soil and plantings as well as maintenance materials can be transported in the cargo space. The tailgate can be moved between a first position where it serves to enclose the storage space and a second position where its serves as a workbench surface. Tool receiving recesses are provided in the sidewall edges of the composite container for transporting small tools such as trimmers, shovels, shears and/or rakes.

    摘要： A dual rate leaf spring suspension supports a frame member over an axle of a small utility vehicle. The dual rate leaf spring suspension includes a full-length leaf spring and a half-length leaf spring. A spacer plate is the only connection point between the full-length leaf spring and the half-length leaf spring, which is positioned intermediate the full-length leaf spring and at one end of the half-length leaf spring.

    摘要： A tubular axle housing is provided with pairs of tabs that protrude or extend from the axle to a height or length sufficient to prevent the intermediate section of a U-bolt from sliding over the tab. The tabs also help locate and guide the U-bolt between the tabs during the assembly of a leaf spring to the axle housing. The tabs provide a positive locking feature for the U-bolts during service of a vehicle, to prevent the U-bolts from moving laterally along the axis of the axle tube. As a result, the joint between the leaf spring and axle housing is more secure.
