Abstract
The invention belongs to the field of high-pressure water jet machines. More precisely, it concerns a hydraulic pumping system for high-pressure water jet machines and the stopping system for a pump (4) when the flow of outgoing liquid is stopped by a manual control (10). The hydraulic system includes in particular a control valve (8) of the pressure zero-setting type, a non-return valve (6) and a pressostat (13) connected to an electric circuit which assumes control of the pump, suitable as a whole for enabling low pressure to be maintained throughout the installation, at least less than the normal working pressure, whilst the outgoing flow is intercepted.
