A water pump (10) and impeller (30) for use in applications such as internal combustion engines. A plurality of holes (40, 44) are formed near the hub and periphery of the impeller (30) of the water pump to provide coolant flow through a cavity (22) housing a seal. The seal (18) is thereby cooled to prevent premature failure of the seal (18) due to overheating.
L'invention a trait à une pompe à eau (10) et à un rotor connexe (30) conçus pour être utilisés avec des applications telles que des moteurs à combustion interne. Une pluralité de trous (40, 44) sont pratiqués près du moyeu, autour du rotor (30) de la pompe pour assurer un flux de refroisdisant passant par une cavité (22) munie d'un joint d'étanchéité. Le joint en question est donc refroidi pour éviter que son intégrité soit compromise par une éventuelle surchauffe.
