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).
Claims21
A pressure amplifier comprising a housing, an amplification piston in the housing having a high pressure area in a high pressure chamber and a low pressure area in a low pressure chamber, and a switching valve having a pressure controlled valve element having a large pressure area and a small pressure area, wherein the valve element and the amplification piston are located in a same bore in the housing, wherein the valve element is located in a part of the bore forming the low pressure chamber, wherein the low pressure chamber has an inner diameter corresponding to an outer diameter of a front part of the valve element, wherein the area of the large pressure area is greater than the area of the small pressure area, and wherein a difference in pressure applied to the large pressure area and the small pressure area causes the pressure controlled valve element to move in a first direction or in a second direction.
A pressure amplifier comprising a housing, an amplification piston in the housing having a high pressure area in a high pressure chamber and a low pressure area in a low pressure chamber, and a switching valve having a pressure controlled valve element having a large pressure area and a small pressure area, wherein the valve element and the amplification piston are located in a same bore in the housing, wherein the valve element is located in a part of the bore forming the low pressure chamber, wherein the low pressure chamber has an inner diameter corresponding to an outer diameter of a front part of the valve element, wherein the area of the large pressure area is greater than the area of the small pressure area, and wherein the small pressure area is configured to be permanently fluidly connected to a supply pressure.
