20090016908 | MULTI-CYLINDER, DRY-RUNNING PISTON COMPRESSOR A COOLING AIR FLOW - A multi-cylinder dry-running piston compressor for generating compressed air. The piston compressor includes a crankcase having an interior and a crankshaft rotatably mounted in the crankcase. Also included are two connecting rods mounted in the crankshaft and configured to run counter to one another. Further included are two cylinders mounted in the crankcase and a piston arranged at an end of each of the connecting rods and configured to run in a respective one of the two cylinders. | 01-15-2009 |
20090071324 | WATER-COOLED PISTON COMPRESSOR - A water-cooled piston compressor having at least one air-compressing piston, which can be driven with means for producing a linearly oscillating drive force and which is accommodated in an axially movable manner in a cylinder housing which is closed at the end face via a cylinder head and is provided with water-cooling means, wherein the water-cooling means comprise a cylinder housing which is formed with a double wall and on whose end face facing the cylinder head a plurality of cooling openings are arranged, via which coolant flowing through the double-walled cylinder housing comes into contact with the region of the cylinder head. | 03-19-2009 |
20090217902 | METHOD FOR ASSEMBLING A CRANKSHAFT DRIVE AND PISTON COMPRESSOR - A piston compressor includes a crankcase having an interior space. The compressor also includes a crankshaft, at least one connecting rod having a connecting rod head that interacts with the crankshaft. The at least one connecting rod and crankshaft are arranged in the crankcase and the crankcase and the at least one connecting rod are of a non-split configuration to permit assembly of the at least one connecting rod on the crankshaft by a threading into the interior space of the crankcase. | 09-03-2009 |
20100054958 | OIL-FREE AIR COMPRESSOR SYSTEM WITH INLET THROTTLE - The present air compressor system includes at least one piston stage connected to the air inlet of the compressor by an inlet valve and connected to the compressed air outlet of the compressor by an outlet valve; a motor driving the piston stage; and an adjustable throttle connected between the air inlet and the inlet valve. A controller controls the motor and the throttle to substantially close the throttle to unload the piston stage when necessary. | 03-04-2010 |
20100158712 | COMPRESSOR WITH DUAL OUTBOARD SUPPORT BEARINGS - A compressor includes a motor having a rotor mounted to a free end of a crank shaft and a stator in a motor housing, and a bearing assembly supporting the crank shaft on the crank shaft housing adjacent the motor housing. The bearing assembly includes a bearing housing mounted to the crank shaft housing and including a bore; and a pair of spaced bearings mounted in the bore of the bearing housing and receiving the crank shaft. The space between the bearings is selected to allow the free end of the crank shaft to deform in synchronization with the movement of the stator and maintain a gap between the rotor and stator over the operating range of the motor. | 06-24-2010 |
20100221128 | Compact Dry-Running Piston Compressor - A compact dry-running piston compressor includes at least one cylinder for the compression of air by a corresponding piston, which may be driven by an electric motor with a crank drive made up of a crankshaft and connecting rod. The crank drive is rotatably mounted in an oil-bath-free compressor housing on pre-lubricated roller bearings and generates an internal cooling air flow inside the housing due to its movement cycle. The compressor housing includes two housing sections separated by a partition wall, in order to accommodate the crank drive within the first housing half and the electric motor in the second housing half. A roller bearing common to the crank drive and the electric motor is arranged in the partition wall lying in the cooling air flow passing through the first housing half. | 09-02-2010 |

20140231169 | SOUND SUPPRESSOR DEVICE FOR AN AIR DRYING UNIT OF A COMPRESSED-AIR SUPPLY SYSTEM - A sound suppressor device for an air drying unit of a compressed-air supply system having a sound suppressor housing on which is arranged an inlet opening for the supply of condensate-laden compressed air to be discharged from the air drying unit and at least one outlet opening for the discharge of the condensate-laden compressed air to the outside, wherein the inlet opening issues into at least one pre-chamber of the sound suppressor housing, which pre-chamber issues into post-chambers which are connected in parallel and which are arranged around a heating rod arranged centrally in the sound suppressor housing. | 08-21-2014 |
20140301873 | CONDENSATE SEPARATOR DEVICE FOR A COMPRESSOR ARRANGEMENT FOR THE PRODUCTION OF COMPRESSED AIR - A condensate separator device for a compressor arrangement for the production of compressed air having a separator housing that has a compressor-side inlet connection and an outlet connection for discharging the dehydrated compressed air. A base-side drainage valve is provided for releasing the condensate, which has collected in the separator housing, into the surrounding environment via a release opening. The valve is pneumatically-piloted seat valve able to be controlled by an electro-pneumatic control valve, and this electro-pneumatic control valve of the drainage valve is arranged outside the separator housing and connected to a pilot connection of the drainage valve via a control pressure-line. | 10-09-2014 |
