| 417243000 | WITH INTERCOOLER | 6 |
| 20090123302 | SCREW COMPRESSOR - A screw compressor comprising: a low pressure stage compressor body; a high pressure stage compressor body that further compresses a compressed air compressed by the low pressure stage compressor body; pinion gears for example, respectively, provided on, for example, a male rotor of the low pressure stage compressor body and, for example, a male rotor of the high pressure stage compressor body; a motor; a bull gear for example, provided on a rotating shaft of the motor; and an intermediate shaft supported rotatably and provided with a pinion gear, which meshes with the bull gear, and a bull gear, which meshes with the pinion gears. Thereby, it is possible to make the motor relatively low in rotating speed while inhibiting the gears from being increased in diameter, thus enabling achieving reduction in cost. | 05-14-2009 |
| 20090110567 | Air Compressor - A compact lightweight air compressor is provided with a DC motor to provide versatile use in the field where no AC power source is available. The air compressor includes a intercooler storage vessel for cooling and storing the compressed air as well as a cooling fan arrangement that allows cooling of all the air compressor components. | 04-30-2009 |
| 20090297368 | Single Piece Water Over Air Intercooler for a Reciprocating Air Compressor - A water over air intercooler for use in a reciprocating air compressor includes a central core unit having an interior which contains a plurality of air passage tubes, a cooling water inlet and at least one cooling water outlet. A first manifold has at least one air inlet and is in communication with the plurality of air passage tubes so as to receive air from the at least one air inlet and direct the air to the plurality of air passage tubes. A second manifold has an air outlet and is in communication with the plurality of air passage tubes so as to receive air from the plurality of finned air passage tubes and direct the air to the at least one air outlet. The central core unit, the first manifold and the second manifold are integrally connected by welding to form a single piece. | 12-03-2009 |
| 20090004029 | MULTISTAGE COMPRESSOR UNIT WITH COOLING DEVICE - A multistage compressor unit consisting of a low-pressure charging device having a low-pressure compressor housing, a high-pressure charging device having a high-pressure compressor housing and a cooling device, characterised in that the cooling device comprises a cooling device housing and the cooling device housing of the cooling device is indirectly connected to the low-pressure compressor housing of the low-pressure charging device and the high-pressure compressor housing of the high-pressure charging device. | 01-01-2009 |
| 20100329895 | MULTISTAGE COMPRESSOR INSTALLATION - A multistage compressor installation in which compression stages utilizing centrifugal compressors are independently driven by drivers that can be electric motors configured to be controlled by a speed controller. Intercoolers are located between stages to remove the heat of compression and the stages are connected such that outlets are located opposite to inlets of the compressors and conduits connecting the intercoolers to the stages are in an in-line relationship to inhibit the formation of pressure drops between stages. The conduits connecting the stages incorporate tapered transition sections configured such that flow velocity gradually decreases towards the intercooler and gradually increases from the intercooler to the next succeeding compression stage to further inhibit pressure drops. | 12-30-2010 |
| 20100290926 | CYLINDER HEAD FOR PISTON REFRIGERATION COMPRESSOR, COMPRESSION UNIT INCLUDING SUCH CYLINDER HEAD, AND PISTON REFRIGERATION COMPRESSOR INCLUDING SAID COMPRESSION UNIT - A cylinder head for a piston refrigeration compressor that includes at least a first part defining a cooling-gas suction chamber and at least a second part defining a cooling-gas discharge chamber, the first and second parts being distinct from each other, and the suction and discharge chambers each being intended to be brought into communication with a compression chamber provided in the compressor. The cylinder head includes thermal insulation means provided between the first and second parts, the thermal insulation means including an insulation chamber defined by the first and second parts. | 11-18-2010 |
