Abstract
A hydraulic device includes a passage block with a first hole, an internal body received in the first hole connected to a hydraulic module and an actuator. The actuator has a cylindrical shell integrally connected at its one side to the passage block and projecting at its other side from the passage block. The passage block has a first and second passageway to communicate the hydraulic module with a groove means on the internal body, and a third passageway to communicate the groove means with a first chamber of the actuator. A connecting member connects the fluid distributor unit to the other side of the actuator to communicate the groove means with a second chamber of the actuator.
