摘要： A road sweeper is provided with a rotatingly drivable sweeping brush, a sweepings container, a suction blower in flow communication with the sweeping brush for taking in dust-containing air, and at least one filter for separating dust from the air drawn in, wherein the filter can be acted upon on the clean side with external air stored in a pressure container and subject to pressure, via at least one external air valve for cleaning. In order for the filter to be cleaned off with as small an amount of external air as possible, the pressure container can have a pressure container wall located opposite the clean side of the at least one filter, the at least one external air valve being arranged on the wall, wherein a section of a suction conduit extends between the pressure container wall and the clean side of the filter.

摘要： A high-pressure cleaning apparatus including a high-pressure pump that includes a suction chamber, at least one pump chamber in which liquid is pressurized, and a pressure chamber arranged downstream of the pump chamber is disclosed. The high-pressure pump includes a return line via which the pressure chamber is in flow communication with the suction chamber, and a valve unit by which a free cross-sectional area of the return line is changeable. The high-pressure cleaning apparatus also includes a drive unit associated with the valve unit, a control unit coupled to the drive unit and a pressure sensor coupled to the control unit for detecting liquid pressure on the pressure side of the pump chamber. Depending on the signal of the pressure sensor, the liquid pressure can be controllable to a predetermined or predeterminable liquid pressure by changing of the free cross-sectional area of the return line.
