Water-cooled internal combustion engine delivery damper comprises deformable damping element on downstream side of pump housing plus runoff channel returning to intake.

摘要

The water pump is the cooling water pump (1) of a water-cooled engine (2) and the displaceable and/or deformable coupling element (6) is arranged in a mounting (5) fitted to the downstream side of the pump housing (4). When the pre-set pressure is exceeded, an opening (7) to a choke runoff channel (8) is opened. The channel integrated in or on the housing (4) issues into the intake connection (9) of the cooling water pump.
