Abstract:
A rotational energy storage device (10) or spring which includes a roller-cam assembly having a shaft (14), a ring (12) rotatably disposed about the shaft, and at least one roller (16) disposed between shaft and ring. The roller (16) is configured such that, upon rotating the ring relative to the shaft, the roller interferes with the ring and the shaft to convert and effect storage of mechanical energy created by the relative rotation of the ring and the shaft. Preferably a plurality of spaced rollers are positioned between ring and shaft. A cam geometry (20) which is symmetrical or asymmetrical is provided on the shaft, the ring, the roller, and combinations thereof. A rotational energy storage device having a back-up ring with alternating thin and thick cross-sectional areas is further provided which is indexed to provide regions of low and high stiffness regions against each roller.
Abstract:
A portable air compressor unit (10) having a housing (22) with a rear end (30) and front end (26). The housing (22) includes a rear louver (66) near the rear end (30), an exhaust outlet (74) near the front end (26) and a mid louver (70) between the rear and front end. A rear cooler set (82) and rear fan (106) are disposed within the housing between the rear louver and mid louver. The fan (106) draws cooling air into the housing through rear louver (66) and through the rear cooler set (82). A front fan (122) and front cooler set (130) are disposed within the housing (22) between the mid louver (70) and exhaust outlet (74).
Abstract:
Apparatus for storing a hose or tools on a portage compressor. One embodiment of a hose storage device includes a support bar, a securing plate, and a locking bar. Another embodiment of a hose storage device includes a bracket, a hose reel, and a roller plate having a hose opening and at least one roller. One embodiment of a tool storage device includes a support structure having a top surface, a side surface, and a bottom surface. The tool storage device also includes a foam layer positioned between the top surface and the bottom surface.
