The invention relates to a cleaning device (100) for a vehicle (1000) for providing at least one cleaning nozzle (320) with a liquid cleaning pulse (FRI) and/or a compressed air cleaning pulse (DRI), comprising:-a module compressed air port (272) for receiving compressed air (DL),-a pressure cylinder (220) having a cylinder volume (VZ), which has a movable separating means (226), the separating means divide the cylinder volume (VZ) in a fluid-tight manner into an air chamber (222), which receives compressed air (DL), and a liquid chamber (224), which receives cleaning liquid (F), the air chamber (222) having an air chamber port (222.1), which can be supplied with compressed air (DL) for filling the air chamber (222), and wherein, when the air chamber (222) is filled, the air chamber port (222.1) can be supplied with compressed air (DL) for filling the air chamber (222); the reduction of the liquid chamber (224) is effected by a movement of the separating means (226) against the restoring force (FR) and an enlargement of the air chamber (222), whereby a cleaning liquid (F) is provided to the liquid nozzle line (626) in the form of a liquid cleaning pulse (FRI) via a liquid chamber port (224.1) of the liquid chamber (224). According to the invention, a switching valve (270) is provided, which is designed to establish a pneumatic connection between the module compressed air port (272) and the air chamber port (222.1) in the intake position (270A). According to the invention also there is provided a bypass valve (330) configured for establishing a pneumatic connection bypassing the switching valve (270) between the module compressed air port (272) and the compressed air nozzle line (278) in the open position (330B, 332B, 334B) for providing a bypass compressed air flow (BDS).

    本发明涉及一种针对车辆(1000)的用于为至少一个清洁喷嘴(320)提供液体清洁脉冲(FRI)和/或压缩空气清洁脉冲(DRI)的清洁设备(100),其具有:‑用于接受压缩空气(DL)的模块压缩空气端口(272),‑具有缸容积(VZ)的压力缸(220),压力缸具有能运动的分隔器件(226),分隔器件以流体密封方式将缸容积(VZ)分成接收压缩空气(DL)的空气腔室(222)和接收清洁液(F)的液体腔室(224),其中,‑空气腔室(222)具有空气腔室端口(222.1),空气腔室端口能被加载压缩空气(DL)用来填充空气腔室(222),其中,在空气腔室(222)被填充时,通过分隔器件(226)抵抗复位力(FR)的运动和空气腔室(222)的增大来实现液体腔室(224)的缩小,由此经由液体腔室(224)的液体腔室端口(224.1)将清洁液(F)以液体清洁脉冲(FRI)的形式提供给液体喷嘴线路(626)。根据本发明设置有切换阀(270),切换阀被构造成用于在进气位置(270A)中在模块压缩空气端口(272)与空气腔室端口(222.1)之间建立气动连接。根据本发明还设置有旁通阀(330),旁通阀被构造成用于在打开位置(330B、332B、334B)中在模块压缩空气端口(272)与压缩空气喷嘴线路(278)之间建立从切换阀(270)旁经过的气动连接,以用于提供旁路压缩空气流(BDS)。
