PRESSURE CONVERTER
Document Type and Number:
Japanese Patent JPS61215801
Kind Code:
A
Abstract:
PURPOSE:To block the over-run of a piston by coupling a large piston and a small piston with the degree of radial freedom and providing an exhaust port in a primary liquid chamber. CONSTITUTION:Threaded portions of connecting members 12, 12' are screwed into threaded portions 10a, 10a' of a piston 10, and heads 11a, 11a' and small diameter portions 11b, 11b' of pistons 11, 11a' are inserted into the piston so that the piston 10, 11, 11' are connected to each other slightly axially and radially movably. Also, an exhaust ports 5a' or 5a of a barrel 5 is opened right before the piston 10 moves left or right and the end face of connecting members 12 or 12' abuts against the opposed end face of barrel 6 or 6'. Thus, the productivity and operability are improved, while the piston can be blocked from over-run.
