Abstract
A bearing housing (1) of an exhaust-gas turbocharger 2, having an oil guide to at least one bearing point (5) in the bearing housing (1). The oil guide is formed by at least one of bores and cutouts in the bearing housing (1). There is formed in the oil guide a siphon (10) which is integrated into the bearing housing (1).
Claims7
A bearing housing (1) of an exhaust-gas turbocharger (2),
- having an oil guide within the bearing housing through which oil flows from an oil supply inlet to at least one bearing point (5) in the bearing housing (1),
- wherein the oil guide is formed by at least one of bores and cutouts in the bearing housing (1), and
- wherein there is formed in the oil guide, when the bearing housing is in the installed orientation, a flow path including a first segment (6) through which oil flows downward, followed by a second segment through which oil flows upward, followed by a third segment (14) through which oil flows downward to said at least one bearing point (5) in the bearing housing (1), wherein an oil collecting reservoir is formed between the first segment (6) and second segment (7) in which oil collects after engine shut-down, which reservoir is integrated into the bearing housing (1).
An exhaust-gas turbocharger (2) having at least one bearing housing (1),
- having an oil guide through which oil flows from an oil supply inlet to at least one bearing point (5) in the bearing housing (1),
- wherein the oil guide is formed by at least one of bores and cutouts in the bearing housing (1), and
- wherein there is formed in the oil guide, when the bearing housing is in the installed orientation, a flow path including a first segment (6) through which oil flows downward, followed by a second segment (7) through which oil flows upward, followed by a third segment (14) through which oil flows downward to said at least one bearing point (5) in the bearing housing (1), wherein an oil collecting reservoir is formed between the first segment (6) and second segment (7) in which oil collects after engine shut-down, which reservoir is integrated into the bearing housing (1), and
- wherein the at least one bearing point (5) is for mounting a shaft (4) which connects a turbine wheel (11) to a compressor wheel (12) of the exhaust-gas turbocharger (2).
