Abstract (en)
[origin: WO8911345A1] High-pressure cleaning apparatus with a jetting pump (2) for a cleaning liquid, which is connected on the suction side to a presettling tank (4) with a feeder pipe for delivering the cleaning liquid, and which has on the pressure pipe a bypass-pipe (7), leading from the pressure pipe to the presettling tank, and with an electromotor (1) that drives the jetting pump (2) and includes a cooling-liquid pipe (11), through which the cleaning liquid flows. Effective cooling of the electromotor (1) of said high-pressure cleaning apparatus is achieved even in the recirculation mode, without loss of cooling liquid, through the fact that the feeder pipe (13) into the jetting pump has a greater conveying capacity than the cooling-liquid pipe (11), the latter leading into the presettling tank (4), which includes filling-height limitation means (15, 16, 17).
