The invention relates to a support and cooling arrangement for a turbocharger apparatus (1) in a big diesel engine. It comprises a uniform body part (2) supported to the engine block (3), provided with a planelike bracket base (18) for supporting the turbocharger apparatus (1) and including a first cooling water duct (11), through which cooling water is arranged to be fed into the turbocharger apparatus (1), and a second cooling water duct (12), through which cooling water is arranged to be led away from the turbocharger apparatus (1). The planelike bracket base (18) includes' connecting openings (19, 20, 21) to the said first (11) and said second (12) cooling water ducts. In addition the arrangement comprises thermostatic valve means (13) arranged in the body part (2) in connection with the said second cooling water duct (12) and which, on the basis of the temperature of the cooling water coming out (10) from the turbocharger apparatus (1), is arranged to lead the cooling water on the one hand for recirculation (14) and on the other hand for cooling (15).
A support and cooling arrangement for a turbocharger apparatus (1) in diesel engine, comprising a uniform body part (2) which is supported to the engine block (3) and is provided with a planelike bracket base (18) for supporting the turbocharger apparatus (1) and includes a first cooling water duct (11), through which cooling water is arranged to be fed into the turbocharger apparatus (1), and a second cooling water duct (12), through which cooling water is arranged to be led away from the turbocharger apparatus (1), the planelike bracket base (18) including connecting openings (19, 20, 21) to the said first (11) and said second (12) cooling water ducts, the arrangement further comprising thermostatic valve means (13) arranged in the body part (2) in connection with the said second cooling water duct (12) and which, on the basis of the temperature of the cooling water coming out (10) from the turbocharger apparatus (1), is arranged to lead the cooling water on the one hand for recirculation (14) and on the other hand for cooling (15).
A diesel engine comprising an engine block, a turbocharger apparatus, and a support and cooling arrangement for the turbocharger apparatus, the support and cooling arrangement comprising a uniform body part which is supported to the engine block and is provided with a planelike bracket base to which the turbocharger apparatus is supported, the uniform body part including a first cooling water duct, through which cooling water is arranged to be fed into the turbocharger apparatus, and a second cooling water duct through which cooling water is arranged to be led away from the turbocharger apparatus, the planeline bracket base including connecting passages to said first and second cooling water ducts, the arrangement further comprising thermostatic valve means arranged in the body part in connection with said second cooling water duct in which, on the basis of the temperature of the cooling water coming out from the turbocharger apparatus, is arranged to lead the cooling water on the one hand for recirculation and on the other hand for cooling.
