An air actuator adapted to be located between a pair of spaced members for moving said members with respect to each other includes a hollow body formed of an expandable non-reinforced polyurethane. The body has an ellipsoidal shape and terminates in a pair of curved closed ends and has an interior pressure cavity for receiving and discharging a pressurized fluid for expanding and contracting the body. The body is formed of at least two half members of the non-reinforced polyurethane by either a ...

A control circuit portion in an air compressor finds the rate of decrease of pressure inside a tank portion when a motor is at rest relative to the time based on a detection signal from a pressure sensor. Where the rate of decrease of pressure is greater than a given value, the motor is started without waiting for the pressure inside the tank to decrease to a motor restart pressure value, the pressure inside the tank portion rises to a given motor stop pressure value and the motor is then contro...

An air cleaner is described wherein an ion wind is generated by an ionizing element and directed to pass over a dust collector surface. By proper design and adjustment of the ionizing element and collector, the unit can be operated without emitting charged particles, if any, in other than the direction of orientation of the dust collector surface and thus avoiding smudging of the surrounding walls. The collector may be cylindrical in form and may be separately detachable, rendering it readily av...

A housing 11 accommodates a pleated filter element 14. A fuel adsorbent member 16 is arranged in the housing 11 at a position downstream from the filter element 14. The fuel adsorbent member 16 adsorbs evaporative fuel leaking from an engine. The fuel adsorbent member 16 includes holding pleats 16g. Each of the holding pleats 16g is received in the space between an adjacent pair of the element pleats 14a of the filter element 14. This maintains the interval between the element pleats 14a. The ho...

An air conditioner is disclosed which includes a damper adapted to select a desired path of air humidified by a moisture release portion of a desiccant wheel in accordance with a humidification or dehumidification mode. In accordance with operation of the damper, humidified air is heat-exchanged in a heat exchanger in the dehumidification mode, so that the air is dehumidified. The dehumidified air is discharged into a room. In the humidification mode, the humidified air is directly discharged to...

In an air conditioner, the air conditioner includes a casing having an indoor space region and an outdoor space region; an indoor unit installed in the indoor space region, sucking air and cooling the sucked air through a first heat exchanger, an outdoor unit installed in the outdoor space region, sucking air and releasing heat of the air to the outside through a second heat exchanger; and a turbo fan installed in the outdoor space region for generating air flows so as to flow air to the second ...

An air cleaner includes a housing, a filter, a photocatalyst reaction unit which can form spiral a air flow, a forced convection device, and an electrocircuit controller. The forced convection device is located between the filter and the photocatalyst reaction unit. Because the air cleaner uses a longitudinal air conduit, an air inlet along a tangential direction of the air conduit and spiral guide vanes at the inlet, air passing through a fan and into the air conduit flows spirally in the condu...

A center portion of a handle housing portion 3 is arranged with a pressure reducing valve mechanism portion 50 for reducing a pressure of high pressure compressed air to be surrounded by an exhaust chamber 40, in a state of making a trigger 37 ON, air pressure P22 of a secondary pressure side port 52 of the pressure reducing valve mechanism portion 50 is made to be higher than air pressure P21 of a secondary pressure side port 52 of the pressure reducing valve mechanism portion 50 in a state of ...

An air-bag arrangement is disclosed, which preferably takes the form of an inflatable curtain. The arrangement comprises a single inflatable element (2) and a gas generator (10), which is configured to inflate the inflatable element (2). The inflatable element (2) defines at least two inflatable chambers (5,6). A gas-supply duct (11) is provided which has an end outlet aperture (19) formed through an end wall 18 of the gas-supply duct (11) so as to have a diameter smaller than the bore of the ga...

The object of the present invention is to improve shooting precision by causing a bullet to be fired before retreating of the slide commences, which is a problem in related art 3. An air gun of the present invention comprises; a slide, a barrel, a cylinder portion, a hit pin, a hollow valve pin chamber, a valve body, a gas supply port, a valve pin, a pressing section, a bullet feed nozzle link connected to a trigger; and a bullet feed nozzle, when the hit pin is pressed to the muzzle side and ma...
