FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to double clutch. Double clutch includes housing (9), packs of friction discs (3–6) arranged concentrically between each other, hydraulic cylinders with pistons (36) and (42). Housing (9) has side wall (11) on which rim (16) surrounding piston (36) located opposite pack of disks (3) and (5) is fixed. Wall (11) is made with outer ring ledge (12), on which piston (36) is located, and with internal annular ledge (13) surrounding piston (42). On ledge (12) there are external and internal gear sections (33) and (34). Piston (36) and disks (3) are engaged with toothed section (33). Discs (6) are engaged with toothed section (34). Cover (58) of compensation chamber (50) is installed inside rim (16) on piston (36). In cylindrical wall of piston (36) in gap between its end wall and cover (58) there is hole (57) located opposite radial hole (56), made in protrusion (12). On two sides of hole (56) two radial seals (55) are installed.

EFFECT: higher compactness.
