Patent number: 10774835Abstract: A vacuum pump with a primarily cylinder-shaped pump housing is provided. A bowl-shaped sound-absorbing cover is attached on the pump housing and a circumferential gap space for sound absorption is formed between the pump housing and the sound-absorbing cover. The pump housing has an end face in which at least one air outlet opening is arranged. An elastic upstream sound absorber element is arranged between the end face and the sound-absorbing cover so that an upstream chamber is formed therebetween into which the air flows from the air outlet opening. The upstream sound absorber element has a molded projection facing the end face with an air channel passing through the projection. The projection is arranged at a distance from the end face during operation of the vacuum pump. While the vacuum pump is idle, the projection makes contact with the end face through elastic deformation of the upstream sound absorber element, causing the air channel to be closed off and creating a check valve function.Type: GrantFiled: November 14, 2016Date of Patent: September 15, 2020Assignee: Hella GmbH & Co. KGaAInventors: Ingo Geue, Theodor Hüser, Christian Praest, Thomas Valeiras Fernandez

Patent number: 9719513Abstract: A pump includes a pump chamber in which a rotor with gates is supported so that it can rotate, an electric motor for driving the rotor, an outlet, and an inlet port that is fastened to a mounting plate and is in active connection with an inlet channel. The pump should be improved so that its service life and reliability are improved with minimal installation complexity in a vehicle, wherein intense cleaning of lines and devices connected on the suction side can be eliminated. This is achieved in that a filter is arranged in the area of the inlet channel between the mounting plate and the pump chamber.Type: GrantFiled: December 12, 2013Date of Patent: August 1, 2017Assignee: Hella KGaA Hueck & Co.Inventors: Ingo Geue, Theodor Hüser, Dietmar Rech, Thomas Valeiras Fernandez

Patent number: 9429159Abstract: A pump includes a pump chamber in which a rotor with gates is supported so that it can rotate, an electric motor for driving the rotor, a muffler that encloses a volume in the area of the pump chamber, wherein the volume is in active connection with an outlet port and a front muffler that is arranged within the muffler. To improve the service life and reliability of the pump in a vehicle with minimal installation expense, it is proposed that a filter is integrated into the front muffler.Type: GrantFiled: December 10, 2013Date of Patent: August 30, 2016Assignee: HELLA KGAA HUECK & CO.Inventors: Ingo Geue, Theodor Hüser, Dietmar Rech, Thomas Valeiras Fernandez
