Abstract

Improvements in multi-dose syringes, characterized by comprising a cylinder; a piston with a built-in stem arranged inside the cylinder to discharge the contents thereof; an inlet valve and a discharge valve, at least one of the valves, preferably the discharge valve, comprising a chamber with inlet and outlet ports; an elastic sheet preferably made of rubber arranged inside the chamber, this sheet with a cross-sectional area considerably larger than the chamber's entrance hole, the plate being normally maintained by a support against the entrance hole, thus closing, the sheet metal is hermetically inlet, but being able to move from the inlet when the pressure on the side of the inlet orifice exceeds that of the side of the outlet orifice so that it allows liquid to pass from the inlet orifice, through the chamber and out, through the outlet hole, returning the sheet to the closed position and being held there by the support, when the excess pressure disappears, in a case when the inlet hole of the the valve has a raised edge, the elastic plate is flat, and in another embodiment the elastic plate arranged inside the chamber of The valve has a raised center section on the inlet port side, which raised center portion is larger in area, although not appreciably larger, in cross section, than the valve chamber inlet port.
