Abstract
Official abstract text for this publication.
In a dynamometer device (1), a dynamometer (5) is placed on a dynamometer-side bed (6), and the dynamometer-side bed (6) is stacked on a tank-side bed (15) located on the top part of a bed tank (3). The dynamometer (5) is connected to the bed tank (3) by an oil discharge pipe (9) which returns a cooling oil (2) to the bed tank (3) from the dynamometer (5). The oil discharge pipe (9) passes through an interface (23) between the dynamometer-side bed (6) and the tank-side bed (15), and extends into the bed tank (3).
First claim
Opening claim text (preview).
The invention claimed is: 1. A dynamometer device, comprising: a tank provided with, at a top part thereof, a flat tank-side bed including an opening part, and storing a cooling medium; a dynamo body provided on a flat dynamometer-side bed forming an interface between the dynamometer-side bed and the tank-side bed, the tank-side bed and the dynamometer-side bed being sealed by a seal surrounding the opening part; and a pipe for returning the cooling medium from the dynamo body to the tank, wherein the pipe communicates with a flow passage extending from an upper part of the dynamo body, is attached to the dynamometer-side bed, and passes through the interface, extends through the opening part located inside the seal and is opened inside the cooling medium inside the tank. 2. The dynamometer device according to claim 1 , wherein the pipe has a cylindrical shape in which a distal end of the pipe is closed, and a plurality of oil discharge holes for discharging the cooling medium in a radial direction of the pipe are provided on an outer peripheral surface of the pipe.
