Patent number: 10060536Abstract: A turbocharger waste gate valve includes an elastically deformable sealing member formed by sheet metal, the sealing member being carried on one of the poppet valve member and the valve housing and being arranged to be under compression between the valve seat and the valve member end face when the poppet valve member is in the closed position so as to be elastically deformed into a compressed state, and to be released from said compression so as to return to an uncompressed state when the poppet valve member is in the open position. The sealing member in the compressed state contacts the valve seat about a full circumference thereof and contacts the valve member end face about a full circumference thereof so as to substantially seal any gap between the valve member end face and the valve seat.Type: GrantFiled: May 30, 2016Date of Patent: August 28, 2018Assignee: Garrett Transportation I Inc.Inventors: Petr Cizek, Antonin Forbelsky, Stanislav Hahn, Vit Micanek
