Claims

[Scope of utility model registration request]

In a bearing lubricating device for a rotating machine in which an oil drain pipe is formed of a double pipe so as to incorporate an oil supply pipe therein, the bearing inlet side of the oil supply pipe and the bearing outlet side of the oil drain pipe are connected through a connecting pipe. What is claimed is: 1. A bearing lubricating device characterized in that a flow rate regulating valve is provided in the path of the communicating pipe.
