Abstract
The invention relates to a cooling water pump for an internal combustion engine with a housing provided with a bearing designed to support a pump shaft and with a sealing element devised to seal the bearing against a working area containing the cooling agent as well as with a leakage chamber receiving the cooling agent that oozes through the sealing element, wherein the leakage chamber is arranged in a recess of the housing and is provided with an opening to the outside, said opening being partially closed by a locking device. A particularly simple way of production is achieved by having the opening closed by a foil, preferably by a metal foil, deposited on a flange facing which is flush with a front surface of the housing.
