Abstract: An air compressor comprises a compressor that compresses introduced air and a tank that stores the compressed air generated by the compressor. The air compressor also comprises a discharge pipe from which the compressed air and a condensate in the tank are discharged to an outside of the tank. The air compressor also comprises a drain cock that is disposed in a passage of the discharge pipe and serves to open and close the discharge pipe. The air compressor also comprises a discharge pipe end portion that includes a discharge port facing upward at a tip end of the discharge pipe. The air compressor also comprises a tubular cover including a top portion that covers the discharge pipe end portion from above.

Abstract: An air compressor includes a motor provided with a basic insulation, a first air compressing unit and a second air compressing unit that are driven by the motor, at least two tanks, and a discharge port. The at least two tanks are connected to the first air compressing unit and the second air compressing unit, store air compressed by the first air compressing unit and the second air compressing unit, and are connected to one another in series. The discharge port is disposed to a tank positioned on a most downstream of supplied compressed air and discharges the compressed air. The motor, the first air compressing unit and the second air compressing unit, and a tank on an upstream side with respect to the tank positioned on the most downstream are electrically insulated from the tank positioned on the most downstream and the discharge port.

Abstract: An air compressor improves the dustproof performance of an intake path to a crankcase. The air compressor includes a compression assembly that reciprocates a piston in a cylinder to produce compressed air, a crankcase accommodating the compression assembly and having an inner inlet to allow outside air to be drawn, a filter located in the crankcase and covering the inner inlet from outside, a filter cover having an outer inlet and covering the filter from outside, and a dust cover covering the filter cover from outside, covering the outer inlet, and including an outer circumferential portion. The outer circumference portion and the filter cover have a space to draw outside air between the outer circumference portion and the filter cover.

Abstract: A driving tool including a first mode wherein a mechanical starting control is performed, and a second mode wherein an electrical starting control is performed, where these modes are configured to be switchable. Only in the second mode, if the elapsed time between the on-operation of a trigger and an on-operation of a contact arm does not exceed a reference time T0, then a second actuation portion can be turned to an on-position to perform a driving operation. In the first mode, in contrast to the electric control, without consuming battery power, the driving operation can be performed by the mechanical control that is made by an operational order of the trigger and subsequently the contact arm. Because of this configuration, even if power supply is shut off, the driving operation by the first mode can be continued.

Abstract: An air compressor includes an internal combustion engine for driving an air compressing part that generates compressed air, which is stored in an air-storage tank. At a point in time when the air pressure inside the air-storage tank has increased to a first set pressure, the supply of fuel to the engine is cut off, thereby stopping the engine and the combustion of fuel. At a point in time when the air pressure inside the air-storage tank has decreased from the first set pressure to a second set pressure, a starter motor is started up to resume the operation of the engine.

Abstract: A portable inflator (1) includes a motor (51), a compression mechanism (6) driven by the motor (51) to compress and discharge air, a main body housing (2), a leg (3), a grip (4), and a manually-operable trigger (41) provided on the grip. The main body housing (2) includes a battery mount part (251) for detachably mounting a battery (8), and houses the motor (51) and the compression mechanism (6). The leg (3) supports the main body housing (2) when a lower surface (31) of the leg (3) is disposed on a placement surface (P). The grip (4) is connected to the main body housing (2) and extends at least substantially parallel to the lower surface (31) of the leg (3). The motor (51) is driven in accordance with pulling of the trigger (41).

Abstract: A driving tool is provided with first and second grease reservoirs for supplying grease to seal rings present on the outer and inner peripheral circumferences of a head valve in contact with a spring guide. Because of this configuration, wearing off of resistance of the seal rings due to gradual loss of grease can be improved and air leakage therefrom can also be prevented, which can improve durability of the driving tool.
