High pressure cleaning device

A pressure washer, comprising:

• a port (2) for a liquid source (17);
• a high-pressure pump (3);
• a main line (5), through which liquid can be conveyed from the port (2) to a spray opening (6) of the main line (5) by the high-pressure pump (3);
• a control element (4) for setting a pressure value (31, 32, 33) for a pressure in the main line (5);
• and
• a pressure regulator (7) that adjusts the pressure in the main line (5) in accordance with the pressure value (31, 32, 33) set by the control element (4),
• wherein the main line (5) has a suction chamber (9) between the port (2) and the high-pressure pump (3),
• wherein the main line (5) has a pressure chamber (10) between the high-pressure pump (3) and the spray opening (6),
• wherein the pressure regulator (7) has a bypass line (12) with a bypass valve (13),
• wherein the bypass line (13) fluidically connects the pressure chamber (10) to the suction chamber (9),
• wherein an open cross-sectional area of the bypass line (12) can be adjusted by the bypass valve (13) to regulate the pressure in the pressure chamber (10),
• wherein the pressure regulator (7) adjusts the open cross-sectional area of the bypass valve (13) depending on the pressure value (31, 32, 33) set by the control element (4),
• wherein the control element (4) is continuously adjustable along a travel path (8),
• wherein a specific pressure value (31, 32, 33) is set based on a position of the control element (4),
• wherein the travel path (8) of the control element (4) has a plurality of travel path sections (21, 22, 23, 21′, 22′, 23′) directly adjacent to one another,
• wherein each travel path section (21, 22, 23, 21′, 22′, 23′) comprises a plurality of different positions (24, 25, 26) of the control element (4),
• wherein a single pressure value (31, 32, 33) is set by the control element (4) in each travel path section (21, 22, 23, 21′, 22′, 23′), and
• wherein at least two of the pressure values (31, 32, 33) are different.
