20090188059 | Pig with an Improved Seal Effect - A pig for conveying a working medium inside a feed line comprises a pig body which can be driven inside the feed line by a pushing medium and which has on one front side a projection with a free front surface. The pig also contains at least one first and one second circumferential sealing element arranged on the pig body which are made of elastomeric material and which are at a distance from each other in the direction of the longitudinal axis of the pig body and which run coaxial to the longitudinal axis of the pig body. The sealing elements can be pressed against the inner wall of the feed line, in that the working medium or the pushing medium bears against a contact surface of the respective sealing element. The contact surface of the sealing element neighboring the front side with the projection is smaller than the contact surface of the other sealing element. | 07-30-2009 |
20110146569 | Apparatus for Deposition of Lacquer Overspray - An apparatus for deposition of lacquer overspray from the used cabin air of painting facilities laden with overspray comprises electrode apparatus and/or several regions of an electrode apparatus allocated to several different deposition surfaces. The several electrode apparatus and/or regions of one and the same electrode apparatus can be charged with high voltage independently of each other. This achieves not only an energy savings but also fault locating in the high voltage range is simplified and emergency operation in case of a breakdown in the high-voltage range is made possible. | 06-23-2011 |
20130216725 | METHOD FOR ELECTROSTATICALLY COATING OBJECTS AND APPLICATION DEVICE - An electrical field is generated between an application device and an object to be coated. At least one corona electrode associated with the application device is connected to ground, and at least one counter electrode associated with the object is connected at least at intervals to a positive potential. A system for electrostatically coating objects having an application device coating material, and an electrical field device having a high-voltage source which generates an electrical field between the application device and an object to be coated. The field device comprises at least one corona electrode associated with the application device, and at least one counter electrode associated with the object, wherein, during the operation of the device, the at least one corona electrode is connected to ground, and the at least one counter electrode is connected at least at intervals to a positive potential. | 08-22-2013 |
20140183383 | VALVE - A valve for use in conjunction with an application device having a valve housing and a valve spindle which bears a sealing element at a first free end outside the valve housing and, within the valve housing, is mounted displaceably between a closed position and a release position. The valve spindle includes at least one first piston element and at least one second piston element, wherein the first piston element is guided in a first piston space and the second piston element is guided in a second piston space, said piston spaces being bounded by the valve housing. A pressure fluid can be supplied in each case to the first piston space and to the second piston space in such a manner that a force acting in the same direction is exerted on the first piston element and on the second piston element. | 07-03-2014 |
20140306035 | ELECTRODE ASSEMBLY AND ELECTROSTATIC ATOMIZER HAVING SUCH AN ELECTRODE ASSEMBLY - The invention relates to an electrode assembly for an electrostatic atomizer, in particular for an electrostatic rotary atomizer, comprising at least one outer electrode and an electric resistance device, which has at least one resistance unit that is connected via an electrode connection to the at least one outer electrode and can be connected via a contact connection to a pole of a high-voltage source. The electrode assembly defines a main axis around which an electric field is built up. The resistance unit comprises a resistance track that runs between the electrode connection and the contact connection and is carried by a carrier substrate. The invention also relates to an electrostatic atomizer having such an electrode assembly. | 10-16-2014 |
20150140235 | METHOD FOR OPERATING A ROTARY ATOMIZER, SPRAY HEAD, AND ROTARY ATOMIZER WITH SUCH A SPRAY HEAD - A bell plate is rotated about a rotational axis, and coating material is supplied to a discharge surface of the bell plate such that the coating material is projected away from the bell plate. A working fluid is blown at least temporarily as a transonic or supersonic flow onto the coating material coming from the bell plate by means of a dispensing device. Furthermore, a spray head for a rotary atomizer is provided for applying a coating material to an object, having a bell plate which can be rotated about a rotational axis and which has a discharge surface, wherein coating material can be supplied to the discharge surface such that the coating material is projected away from the bell plate. A dispensing device which can blow a working fluid at least temporarily as a transonic or supersonic flow onto the coating material coming from the bell plate. | 05-21-2015 |
20150226211 | Four-Valve High Pressure Pump - A four-valve high pressure pump having a drive and a pump part with a piston capable of moving in a cylinder. Two cylinder blocks are arranged on the ends of the cylinder, through which blocks a transition duct runs. The inlet for the medium to be pumped is provided on an inlet casing part. A medium duct communicating with the inlet extends through the inlet casing part, in which duct a non-return valve is arranged either side of the opening for the inlet and which communicates at each opposing end with a transition duct of a cylinder block. An outlet casing part is constructed in a similar fashion, with an outlet for the medium instead of the inlet. The inlet casing part and/or the outlet casing part is detachably fastened laterally on the cylinder blocks at the side in such a manner that it can be removed without further dismantling the pump part. | 08-13-2015 |
20150328655 | APPLICATION ROBOT HAVING A CONNECTION UNIT FOR DIFFERENT APPLICATORS - The invention relates to an applicator connection unit for an application robot for coating objects having supply lines for an applicator. An applicator can be fastened on the applicator connection unit in such a way that working lines of the applicator are connected to the supply lines of the applicator connection unit. The applicator connection unit is formed as an adapter unit in such a way that at least one applicator of a first mode of operation and one applicator of a second mode of operation can be releasably and replaceably fastened to the applicator connection unit. The invention further relates to an application robot and a system for coating objects, wherein such an applicator connection unit is used. | 11-19-2015 |
