Abstract: Apparatus for storing a hose or tools on a portable 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.

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: A pump comprises a housing having a fluid inlet and a fluid outlet. A piston is mounted for reciprocating motion in first and second directions within the housing. The housing has first and second cavities on first and second sides of the piston, respectively. The first and second cavities are fluidly coupled to the fluid inlet and fluid outlet, so that fluid is pumped to the fluid outlet when the piston moves in either of the first and second directions. A bleed valve is coupled between the first and second cavities. The bleed valve has first and second closed states and an open state. The bleed valve changes from the first closed state through the open state to the second closed state when the piston moves in the first direction. The bleed valve changes from the second closed state through the open state to the first closed state when the piston moves in the second direction.
