1. 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 bearin
1. 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), andwherein 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). 2. The bearing housing as claimed in claim 1, wherein the first segment (6), second segment (7) and third segment (14) of the oil guide are straight bores, respectively, and wherein the second segment (7) is closed off at one end by means of a plug (9). 3. The bearing housing as claimed in claim 2, wherein the plug (9) is a heating element (15). 4. The bearing housing (1) as claimed in claim 1, wherein said at least one bearing point (5) comprises first and second axially separated bearing points, and wherein an oil passage (8) is provided in said oil guide for axially distributing oil to said first and second axially separated bearing points. 5. 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), andwherein 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), andwherein 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). 6. The exhaust-gas turbocharger (2) as claimed in claim 5, wherein the first segment (6), second segment (7) and third segment (14) of the oil guide are straight bores, respectively, and wherein the second segment (7) is closed off at one end by means of a plug (9). 7. The bearing housing as claimed in claim 6, wherein the plug (9) is a heating element (15).
