Abstract

PURPOSE: To make it possible to obtain high control precision by placing a diaphragm at a horizontal position in operation by equalizing the lock distance between a plunger and hook to the stroke distance of a sheet part.
CONSTITUTION: In a proportional electromagnetic mechanism part, core 2 is provided to the center part of coil 1 formed in a hollow cylinder shape and at one end of core 2, sheet member 3 in a needle valve shape and valve plunger 4 forming valve mechanism 5 are provided opposing to core 2. On the other hand, a pressure control mechanism consists of hook 7 hooking plunger 4 mechanically and diaphragm 6, and the movement of plunger 4 is controlled in response to the pressure variation of either one. In this case, the locking distance between plunger 4 and hook 7 is equalized to the stroke distance of the sheet part. Consequently, diaphragm 6 is placed at a horizontal position in operation, and consequently the rigidity of a film decreases to a minimum, so that sheeting performance can be improved with high control precision by using the needle valve.
