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 actuator (1) is disclosed comprising a cylinder housing (2), a piston (5) with a piston rod (6) being displaceably arranged inside the cylinder housing (2) and a pressure amplifier (10) comprising an inlet section (18) with a pressure inlet port (20), an active section (19) with a high pressure outlet port (22), a low pressure chamber (32) and a high pressure chamber (38a). It is an objective of the invention to provide a hydraulic actuator (1) with a modular pressure amplifier (10). To this end, the inlet section (18) is arranged inside the piston rod (6), and wherein the low pressure chamber (32) is stationarily arranged relative to the inlet section (18).

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 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.
