Patent number: 7201569Abstract: Disclosed is a screw compactor comprising two screw rotors which are disposed in screw rotor bores inside a compressor housing and compress a coolant that enters at a coolant inlet and discharge said coolant at a coolant outlet, and a coolant inlet that is arranged within the compressor housing, said coolant being supplied by a coolant-injecting device via a conduit system in order to additionally cool the screw compressor. The inlet is disposed so as to extend into compression spaces that are enclosed by the screw rotors and the screw rotor bores. The aim of the invention is to create a screw compactor in which the compressive oscillations occurring at the inlet do not travel at all or only in an attenuated manner into the conduit system for the coolant-injecting device.Type: GrantFiled: June 2, 2005Date of Patent: April 10, 2007Assignee: Bitzer Kuehlmaschinenbau GmbHInventor: Klaus Hossner

Patent number: 6898948Abstract: In order to provide a screw compressor comprising two screw rotors which are disposed in screw rotor bores in a compressor casing and which compress a refrigerant entering at a refrigerant inlet and discharge it at a refrigerant outlet, and comprising an inlet provided in the compressor casing for refrigerant which is coming from a subcooling circuit and is passed to the inlet in a system of lines, the inlet being disposed in such a way that it opens out into compression spaces enclosed by the screw rotors and screw rotor bores, in which compressor the pressure oscillations or pulsations occurring at the inlet propagate as little as possible to the pipeline system of the subcooling circuit outside the compressor casing, it is proposed that the inlet is preceded by a damper channel which is associated with the system of lines and in which refrigerant from the subcooling circuit is present.Type: GrantFiled: September 3, 2003Date of Patent: May 31, 2005Assignee: Bitzer Kuehlmaschinenbau GmbHInventors: Stephan Roelke, Klaus Hossner

Patent number: 6276911Abstract: In order to improve a screw compressor comprising a housing with a rotor chamber, two screw rotors arranged in the rotor chamber, a slide for controlling the capacity adjoining the rotor chamber, an adjusting device comprising a cylinder and an associated control device with which an inflow and a return flow of the medium provided for actuating the cylinder is controllable in a continuous control mode, such that the control device operates reliably, it is proposed that the cylinder chamber comprise a return flow opening and an intermediate return flow opening, and that the control device activate the return flow opening in the control mode for continuous control in a partial control range between an intermediate position and a minimum position, and activate the corresponding intermediate return flow opening defining the intermediate position for continuous control of piston positions outside of the partial control range.Type: GrantFiled: July 25, 2000Date of Patent: August 21, 2001Assignee: Bitzer Kuehlmaschinenbau GmbHInventors: Karl-Joachim Krusche, Klaus Hossner, Wolfgang Sandkoetter

Patent number: 4683190Abstract: Process for lowering the viscosity of coating solutions containing a thixotropy-causing filler for the production of light-sensitive reproduction materials by adding at least one compound corresponding to one of the following formulas: ##STR1## wherein R is a linear saturated or unsaturated hydrocarbon chain having 2 to 12 carbon atoms, optionally substituted in which one or more carbon atoms can be replaced by N(R.sub.5), O, S, and/or an aromatic radial, or a 5 to 8 membered aliphatic ring.R.sub.1 to R.sub.4 are H, alkyl, aryl, and aralkyl, whereby R.sub.1 to R.sub.4 can be the same or different;R.sub.5 is R.sub.1 to R.sub.4 ;R.sub.6 and R.sub.7 are R.sub.1 to R.sub.4, --(CHR.sub.8).sub.p --OH;p is 1 to 6;q and r are 1 to 6 and can be the same or different;R.sub.8 is H, alkyl;R.sub.9 and R.sub.10 are H, alkyl, --(CHR.sub.8).sub.p --OH.Type: GrantFiled: December 18, 1985Date of Patent: July 28, 1987Assignee: E. I. Du Pont de Nemours and CompanyInventors: Manfred A. J. Sondergeld, Dietmar Dudek, Klaus Hossner
