摘要： A hydraulic transformer (1) comprises a housing (2) including a high-pressure connection (3), a low-pressure connection (4) and an operating pressure connection (5), a barrel member (19, 20) which is rotatably mounted in the housing (2) and provided with a plurality of compression chambers of which the volume changes upon rotating the barrel member (19, 20). A back side (24) of the barrel member (19, 20) includes barrel ports (27) which communicate with the respective compression chambers. The hydraulic transformer (1) has a face plate (28, 29) which is supported by the housing (2) and provided with a front side (30) that supports the back side (24) of the barrel member (19, 20), a back side (31) that faces the housing (2), a circumferential outer wall and a central hole (49) that is surrounded by a circumferential inner wall. The face plate (28, 29) is rotatable with respect to the housing (2) within a predetermined angle, wherein the front side (30) is provided with three arcuate face plate ports along which the barrel ports (27) travel upon rotating the barrel member (19, 20). The face plate ports communicate with the high-pressure connection (3) through a first passage (35) in the face plate (28, 29), the low-pressure connection (4) through a second passage (36) in the face plate (28, 29) and the operating pressure connection (5) through a third passage (37) in the face plate (28, 29), respectively. One of the first to third passages (35, 36, 37) has an opening at the back side (31) of the face plate (28, 29), one of the first to third passages (35, 36, 37) has an opening at the circumferential outer wall of the face plate (28, 29) and one of the first to third passages (35, 36, 37) has an opening at the circumferential inner wall of the face plate (28, 29).
