机动车真空泵
摘要：
本发明涉及一种机动车真空阀(10)，其具有泵室(12)，泵转子在泵室(12)中压缩式地转动，排出室(14)，被压缩的气体从泵室(12)流出至排出室(14)中，分隔壁(22)，其将泵室(12)与排出室(14)分开，在分隔壁(22)中的构造为止回阀的排出阀(20)，压缩气体通过排出阀(20)从泵室(12)流至排出室(14)中。排出阀(20)由在分隔壁(22)中的阀口(24)和具有封闭体(42)的阀体(40)构成。在分隔壁(22)的排出侧上围绕阀口(24)地配设阀座(30)，在其闭合位置中阀体(40)的封闭体(42)的对应的部分贴靠在阀座(30)上。阀座(30)和/或封闭体(42)的对应的部分具有多个微型槽(32)，该微型槽在横向定向。
摘要（英）：

A motor vehicle vacuum pump includes a pumping chamber in which a pump rotor rotates to compress a gas, an outlet chamber into which the gas exits, a separation wall which includes a valve opening and a valve seat arranged on an outlet side of the separation wall around the valve opening. The separation wall separates the pumping chamber from the outlet chamber. An outlet valve is formed as a non-return valve in the separation wall. The outlet valve is formed by the valve opening in the separation wall and includes a valve body with a closing body. The outlet valve has the gas exit therethrough from the pumping chamber into the outlet chamber. A corresponding part of the closing body is supported on the valve seat when the closing body is in a closed position. The valve seat and/or the corresponding part of the closing body includes microgrooves.
