ABSTRACT:
A high pressure cleaning device with a housing (1) containing a driving motor and a pump for cleaning fluid, in particular water, and a bypass valve arrangement, with a valve pistol (2) having a cleaning lance (3) or the like connected thereto, and with a high pressure line (4) leading to valve pistol (2) from a high pressure connection (4) on a housing (1). When the valve pistol (2) is closed, the pump continues to run and circulates, via the bypass valve arrangement, a finite, small volume of cleaning fluid. When the valve pistol (2) is in the closed position, a leakage flow passage having a very high flow resistance remains open, so that, even when the valve pistol (2) is in the closed position, a small leakage flow of cleaning fluid constantly drains out, and is replaced by a corresponding amount of fluid which flows in on the intake side of the pump and cools the circulating fluid.
