内燃机和用于阀致动器的气动操作的气体处理系统
摘要：
本发明涉及一种内燃机，包括：可控的第一发动机阀(8)，第一发动机阀布置成选择性地打开/关闭被包括在所述内燃机(1)中的燃烧室(7)；和气体处理系统，气体处理系统布置成驱动第一发动机阀(8)，该气体处理系统包括气动的闭合压力流体回路，其中，所述闭合压力流体回路包括相互串联联接的压缩机(31)和阀致动器(10)，所述阀致动器操作地连接到第一发动机阀(8)，其特征在于，所述气体处理系统还包括气体蓄积器(38)，所述气体蓄积器经由第三气体蓄积器导管(47)连接到所述闭合压力流体回路的压缩机(31)，所述气体蓄积器导管包括可控阀(48)。本发明还涉及一种用于对阀致动器进行气动控制的气体处理系统。
摘要（英）：

A combustion engine includes, a first controllable engine valve (8) arranged to selectively open/close a combustion chamber (7) included in the combustion engine (1), and a gas handling system arranged to drive the first engine valve (8), which gas handling system includes a closed pneumatic pressure fluid circuit, wherein the closed pressure fluid circuit includes, coupled in series with each other, a compressor (31) and a valve actuator (10) that are operatively connected to the first engine valve (8). The combustion engine is characterized by the gas handling system further including a gas accumulator (38) that is connected with the compressor (31) of the closed pressure fluid circuit via a third gas accumulator conduit (47), which includes a controllable valve (48). A gas handling system for pneumatic control of a valve actuator is also described.
