Title: A HYDRAULIC DEVICE, A METHOD OF MANUFACTURING A HYDRAULIC DEVICE AND A GROUP OF HYDRAULIC DEVICES
Abstract:
A hydraulic device (1) comprises a housing (26), a shaft (2) which is mounted in the housing (26) and rotatable about a first axis of rotation (4). The shaft (2) has a flange (9) extending transversely to the first axis (4). The hydraulic device (1) comprises a plurality of pistons (10a) which are fixed to the flange (9) at equiangular distance about the first axis of rotation (4), a plurality of cylindrical sleeves (11a) cooperating with the pistons (10a) to form respective compression chambers (12) of variable volume, wherein the cylindrical sleeves (11a) are rotatable about a second axis (18) of rotation which intersects the first axis (4) of rotation by an acute angle (α±β) such that upon rotating the shaft (2) the volumes of the compression chambers (12) change. The hydraulic device (1) comprises a barrel plate (15a) which is rotatable about the second axis and which has a first side for supporting the cylindrical sleeves (11a), wherein the first side is directed to the pistons (10a), and an opposite second side which is supported by a supporting surface (20) of a plate-shaped face element (7a) which is fixed to the housing (26). The supporting surface (20) lies in a first plane (21a). The face element (7a) has a back side (23) which is located opposite to the supporting surface (20) and supported by the housing (26). The back side (23) lies in a second plane (22a). The first plane (21a) is angled with respect to the second plane (22a). The angle between the first plane (21a) and the second plane (22a) is smaller than said acute angle.
