Patent number: 10927836Abstract: Method for cooling a liquid-injected compressor element, where a liquid is injected in the compression chamber of the compressor element (2) via an injection valve (13). The method includes the step of adjusting the quantity of liquid which is injected in the compression chamber of this compressor element (2) as a function of a specific adjusting parameter, irrespective of any other possible adjustments. The quantity of liquid to be injected is adjusted by using a second injection valve (19), which has the shape of an adjustable valve to this end.Type: GrantFiled: March 25, 2009Date of Patent: February 23, 2021Assignee: ATLAS COPCO AIRPOWER, NAAMLOZE VENNOOTSCHAPInventor: Kristof Adrien Laura Martens
