Abstract (en)
[origin: WO2019166207A1] The invention relates to a device for providing fluids under a specifiable pressure for the pressure supply of a consumer, such as a working unit (1) of an SCR (selective catalytic reduction) system for treating the exhaust gas of internal combustion engines, comprising at least one pump (3), which, in a fluid circuit (4) formed between a fluid reservoir (5) and the consumer (1), draws the fluid in question from the fluid reservoir (5) and feeds said fluid to the consumer (1). Said device is characterized in that a line branch (9), which contains a throttle point (18), and a valve assembly (23, 59, 61, 63) are provided in the fluid circuit (4), which valve assembly can be actuated into a switching position connecting the fluid reservoir (5) to the pump (3), in which switching position a flow path containing the line branch (9) having the throttle point (18) is formed, and which valve assembly can be actuated into a second switching position interrupting the supply of the consumer, in which second switching position a flow path connecting the pump (3) to the surroundings (57) is formed.
