CHAMBER FOR ABRASION TEST FOR PERFORMING ABRASION TEST FOR VALVE AND VALVE SEAT UNDER THE SAME CONDITION OF COMBUSTION CHAMBER

摘要

PURPOSE: An abrasion test chamber is provided to allow a user to perform an abrasion test for a valve and a valve seat in the abrasion test chamber under the same condition of a combustion chamber. CONSTITUTION: An abrasion test chamber(1) includes a measurement unit(2), a valve guide block, a valve seat fixing block and a burner. The measurement unit(2) measures a gap(412) between a valve(400) and a valve seat(401). The measurement unit(2) includes a body, a linear variable differential transformer(201) inserted into the body, a clamp, a thermal transfer reducer(203), a flange(204), and a bearing(205). An upper portion of the body is shaped in the form of a collet chuck. The linear variable differential transformer(201) is connected to the thermal transfer reducer(203).
