Abstract: A hydraulic pressure intensifier (1) is described comprising a housing (2) having a low pressure chamber (3) and a high pressure chamber (4), force transmitting means (5) between the low pressure chamber (3) and the high pressure chamber (4), and a switching valve (8) connecting the low pressure chamber (3) to a first pressure or to a second pressure different from the first pressure. It is intended to have a large volume on the high pressure side of the pressure intensifier. To this end the switching valve (8) is controlled by a pilot valve 18.

Abstract: A pressure amplifier (1) is described comprising a housing (2), an amplification piston (5) in the housing (2) having a high pressure area (9) in a high pressure chamber (5) and a low pressure area (8) in a low pressure chamber (3), and a switching valve (11) having a pressured control valve element having a larger pressure area (16) and a small pressure area (17). Such a pressure amplifier should have a high operating frequency. To this end the valve element (10) and the amplification piston (5) are located in a same bore (3, 4) in the housing (2).

Abstract: A hydraulic pressure amplifier arrangement (1) is described comprising a supply port (A1), a pressure outlet (A2) connected to the supply port via check valve means (3), a tank port (B1), an intensifier section (5) having a high pressure piston (6) in a high pressure cylinder (7) which is connected to the pressure outlet (A2), a low pressure piston (8) in a low pressure cylinder (9) and connected to the high pressure piston (6), an intermediate space (11) between the high pressure piston (6) and the low pressure piston (8), a control valve (12) controlling a pressure in the low pressure cylinder (9), and a feeder arrangement of the intensifier section (5) including an input connection (19) connected to the supply port (A1) and a return connection (20) connected to the tank port (B1). Such a pressure amplifier arrangement should have a simple construction. To this end the feeder arrangement (19, 20) comprises throttling means (21).

Abstract: A double acting hydraulic pressure intensifier (1) is described comprising a housing (2), a first piston arrangement (7) having a first high pressure piston (8) in a first high pressure chamber (3) in the housing (2) and a first low pressure piston (9) in a first low pressure chamber (5) of the housing (2), a second piston arrangement (10), having a second high pressure piston (11) in a second high pressure chamber (4) in the housing (2) and a second low pressure piston (12) in a second low pressure chamber (6) in the housing (2), and a switching valve (14) having a valve element (15). Such a pressure intensifier should be made compact. To this end the switching valve (14) is located between the first piston arrangement (7) and the second piston arrangement (10).

Abstract: A pressure amplifier (1) is described comprising a housing (2) a low pressure chamber (9-12), a high pressure chamber (13-16) and for transmitting means between the low pressure chamber (9-12) and the high pressure chamber (13-16). Such a pressure amplifier should have a compact design. To this end the force transmitting means comprise a rotor (3) arranged in a bore (4) of the housing (2), wherein the rotor (3) comprises a radially extending low pressure wing (5, 6) and a radially extending high pressure wing (7, 8), the low pressure wing (5, 6) together with the housing (2) delimiting the low pressure chamber (9-12) and the high pressure wing (7, 8) together with the housing (2) delimiting the high pressure chamber (13-16), wherein a supply of fluid into the low pressure chamber (9-12) causes a rotation of the rotor (3) and a rotation of the rotor causes a decrease of volume of the high pressure chamber (13-16).
