摘要

The device has a core housing (6) having coaxial portions (7, 9) delimiting an annular space in which an end of a camshaft is mounted, where the portion (7) is adapted to transmit an engine torque to the camshaft. The portion (9) is provided with a hole (17) extending along an axis and receiving a sampling unit of a vacuum pump (3), where the two portions are connected between them by a radial end wall (8). The sampling unit (18) is adapted to sample a lubricating fluid transported inside the camshaft, where the portions and wall are single block.
