Abstract

PURPOSE:To prevent inspection error owing to poor bend matching of a valve for an engine, galling of foreign matters such as sand and dirt, by providing a valve bend matching station with a pressure gas supply means and a valve opening-closing means. CONSTITUTION:After a positioning is performed to engage a positioning hole W7 of a cylinder head with a positioning pin 14 of a first sealing disc, a drive cylinder 15 is driven to lift the first sealing disc 11 and a cylinder head W is supported securely while an operation chamber W3 is sealed up with a seal material 12. Then, when a pressure air is supplied to operation chambers W3 of the cylinder head through an air injection port 13 to drive a valve opening- closing device 18, bend matching is performed with the opening or closing of valves W1 and W2 while foreign matters such as sand and dirt adhering to the valves W1 and W2 and a valve sheet W6 is removed. Thereafter, the sealing discs abut exhaust paths W5 and W4 of the cylinder head and a pressure gas is supplied to inspect airtightness of the valves.
