BENCH FOR FATIGUE TESTING OF PRECISION PAIRS OF DIESEL FUEL EQUIPMENT Russian patent published in 2013 - IPC G01N3/32 

FIELD: testing equipment.

SUBSTANCE: bench comprises a body, a device for static loading and a mechanism for cyclic loading, comprising a pusher, an axis and a drive of axis rotation. Inside the body there is a fixed sample installed, above which there is a drain hole in the body, connected by the pipeline with the receiving reservoir. The pusher pulled with a guaranteed gap through the central hole arranged in the fixed sample may interact by one end with the movable sample, and by the other one - with a cam made in the form of a steeply breaking spiral and installed on the axis. In the device for static loading, which is connected with a movable sample by means of a spring, there is a through hole that connects the inner cavity, between the movable sample and the device for static loading, with the pipeline of the supplying reservoir.

EFFECT: increased validity of results of laboratory tests of fatigue wear of precision pairs of diesel fuel equipment.
