Abstract

PURPOSE:To measure a stroke value with high precision by thrusting in a primary piston and measuring a change in thrusting force when a piston has a stroke by means of either a length measurement instrument or a load gauge. CONSTITUTION:The dimensions of a primary spring 5 are limited by a spring bearing 4 and a primary piston 6 and the primary spring 5 is compressed to a prearranged length. Next, the same pressure is applied to a primary chamber 8 and an air-tight chamber 18 through the intermediary of primary piping 10 and air-tight chamber piping 14 so that a secondary chamber 7 may be exposed to an atmosphere or at a vacuum pressure by means of secondary piping 10. A secondary piston 3 is allowed to slide as far as its tip touches the bottom of a cylinder 1. After this process, a rod 15 is thrusted in and measurement of each piston stroke is measured. The secondary stroke part is measasured by means of a length measurement of a primary stroke part is begun.
