The invention relates to an improved low-loss cleaning system (1) for installation in a vehicle for cleaning a transparent element (2) of an optical or optoelectronic apparatus (3). In order to optimise the cleaning with minimal fluid use, with different cleaning fluids of different viscosities in a wide temperature range, according to the invention, the cleaning system (1) has a supply pump (4),which conveys a cleaning fluid from a storage container (5) with a supply pressure (Pv) into a hydraulic line (6) in the direction of a cleaning unit (7) with a spray nozzle (8) for applying cleaningfluid to the transparent element (2), wherein a device (9) is interconnected in the hydraulic line (6), which blocks the hydraulic line (6) in the back-flow direction (R) and, during activation, supplies the cleaning unit (7) connected downstream with a working pressure (Pa) that is increased relative to the supply pressure (Pv).
本发明涉及一种改进的损失少的清洁系统(1),其安装在车辆中,用于清洁光学设备或光电设备(3)的透明元件(2)。为了优化在宽域温度范围内在不同粘度时不同清洁流体的最小液体使用量的情况下的清洁,根据本发明提出,清洁系统(1)具有供给泵(4),该供给泵将清洁流体从储存容器(5)以供给压力Pv朝向清洁单元(7)输送到液压管路(6)中,该清洁单元具有喷嘴(8),用于将清洁流体施加到透明元件(2)上,其中,在液压管路(6)中插设有装置(9),该装置在返回方向(R)上关断液压管路(6)并且在激活时为连接在下游的清洁单元(7)以高于供给压力(Pv)的工作压力(Pa)进行供给。
