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.

Storage devices for portable compressors

Portable air compressor enclosure

A machine including a fluid compressor; a generator; a prime mover operably connected to the compressor and the generator; a machine switching means for switching the machine to a first mode of machine operation where only the compressor is operable, to a second mode of machine operation where only the generator is operable, to third mode of machine operation where neither the compressor nor the generator are operable, or to a fourth mode of machine operation where both the compressor and generator are operable.

Machine with at least two modes of operation and switching means for

A portable compressor, which includes a compressor airend for compressing a fluid; a prime mover operably connected to the airend to drive the airend and thereby compress the fluid; and a portable compressor housing which defines a housing chamber having a chamber temperature. The compressor means and prime mover are located in the chamber. The housing has a first end and a second end and means formed thereon to provide for ambient air to flow through the first and second ends and into the housing chamber. The portable compressor also including a housing chamber temperature optimizing system comprising: fan for drawing ambient air through the housing ends. The fan is adapted for movement in a first direction to draw ambient air through the first housing end and in a second direction to draw ambient air through the second housing end. The system also includes a chamber temperature measuring member located in the housing chamber; and a motor for moving the fan. The motor is operably connected to the fan and is also in signal receiving relationship with the temperature measuring member. The motor is adapted to move the fan in a first direction to draw ambient air through the first housing end when the housing chamber temperature is above a set point temperature, and to move the fan in a second direction to draw ambient air through the second housing end when the housing chamber temperature is below a set point temperature.

A portable collapsible tower including a frame, at least one stationary tower member fixed to the frame and at least one movable tower member movable along the exterior portion of the stationary tower member relative to the stationary member. A coupling, movably couples the stationary and movable tower members for movement along the exterior portions. At least one cable located along the exterior portions of the tower members, is used to extend and retract the tower members and a light or tool support bar. As the tension in the one or more cables is altered by a tension altering device, the support bar and tower members are moved between fully extended and fully retracted positions.

A towing assembly for towing a portable machine across a surface includes a drawbar assembly pivotally connected to a frame member of the machine, to permit the drawbar assembly to be pivotable between a first towing position a second support position. An adjustable support assembly is removably connected to the machine for selectably supporting one end of the machine on the surface.

An integral separator and cooling apparatus is provided for removing a lubricant from a heated, compressed lubricant and gas mixture, and for cooling the separated lubricant. The apparatus includes a lubricant reservoir for containing a liquid lubricant. A receiving plenum is made integral with the lubricant reservoir. The receiving plenum has an inlet for receiving the heated, compressed lubricant and gas mixture, a first outlet through which a heated, compressed gas exits, and a second outlet through which the separated lubricant flows from the receiving plenum. An apparatus is provided within the receiving plenum which causes a liquid lubricant to precipitate from the lubricant and gas mixture. A cooling core is made integral with the lubricant reservoir and the receiving plenum. The cooling core fluidly communicates with the lubricant reservoir and with the receiving plenum. The cooling core includes: a header apparatus mounted on the cooling core, a first flow passage which extends from the second outlet of the receiving plenum to the header apparatus, and a second flow passage which extends from the header apparatus to the lubricant reservoir. An apparatus directs a flow of cooling fluid across the first and second flow passages in response to a control signal from a thermal control apparatus.

An air compressor pressure regulating system which controls the operation of an air compressor. A variable speed driver, which is controlled by a throttle, controls the speed of the driver. A compressor valve integrally regulates the airflow to the compressor inlet. The pressure regulating valve is connected between the compressor outlet and a closed reservoir. The pressure existing in the closed reservoir directly effects both the operation of the compressor throttle and the compressor valve. The pressure regulating valve includes of two movable diaphragms (or pistons), which are spaced parallel to each other and which are connected to each other by a rigid connecting member producing similar motion in both diaphragms. The compressor outlet pressure is exposed to the first side of the first diaphragm. The reservoir pressure is exerted on the second side of the first diaphragm as well as the first side of the second diaphragm. An adjustable spring force and the vented atmosphere act on the second side of the second diaphragm. When the compressor outlet reaches a sufficient pressure, dependent on the reservoir pressure, both diaphragms will be jointly raised toward their respective second sides, and compressed air will be permitted to freely flow from the compressor outlet area to the closed reservoir.

Air compressor pressure regulating valve system

The invention comprises incorporating in the wall of a typical unloader valve for a compressor, a normally-closed, pressure-responsive valve for admitting product compressed air therethrough, into the valve chamber, for re-circulation of the admitted air through the compressor. In the first embodiment illustrated, a pilot air pressure, which modulates the unloader valve throttling piston, is also addressed to a passageway which opens onto the normally-closed valve. When the pilot air pressure is substantially elevated, the normally-closed valve opens.

Unloader valve having bypass valving means

The system comprises a conventional oil/gas separator, with an oil supply line extending from the separator oil reservoir for conducting oil to a machine (such as an associated gas compressor, or the like), and a gas/oil vapor line communicating with the gas chamber of the separator, for conducting oil vapor-laden gas thereto (from such a compressor, or like machine). In an embodiment of the improvement, a check valve is interposed between the oil supply line and the reservoir to prevent oil flow from the line to the reservoir, and a by-pass line, having a pilot-pressure-closed, normally-open valve interposed therein, is coupled between the oil supply line and the gas chamber. The valve senses chamber pressure and, when the latter is sufficiently diminished, opens the by-pass line to evacuate the oil supply line (and oil cooler and filter) into the separator. The improvement dramatically inhibits oil foaming and, among other benefits, this makes possible the use of a relatively small and, hence, inexpensive separator. The methods define the steps to be performed in modifying a conventional oil supply system (a) to incorporate the improvement therein, and (b) to control oil flow on shutdown to inhibit oil foaming.
