Discharge mechanism for liq. filled housing - has piston in air-tight cylinder, dividing it into two pressure engageable and releasable chambers

摘要

The piston (8), dividing the air-tight cylinder (4) into two pressure chambers (14,15), is overhung on an axially slidable plunger rod (5) between two stops (9,10). One cylinder front side has an aperture for a sealing passage of a perforating punch (7) at one plunger rod side. At this side there is a funnel-shaped, elastic extension (13) for sealing abutment against the housing (3) with a liq. discharge (13a). The stop positions and the plunger rod sliding rate are so chosen that the punch, in its rest position leaves the extension free. USE/ADVANTAGE - For extracting recyclable liq. in car scrap yards, with easy transport and reliable liq. discharge without environment pollution.
