SYPHON OR SOLIDS HAVING A PISTON WHICH IS CONNECTED WITH A SUSPENSION ARRANGEMENT

摘要

A syphon for solids includes a piston movable in a cylinder to produce an underpressure which is communicated to an attachment for the cylinder in order to permit the attachment to engage the solid material to be lifted. The syphon includes a locking mechanism which connects the cylinder space with the piston during every second stroke of the piston to prevent the formation of a vacuum. The arrangement includes an auxiliary vacuum pump which is connected with the suction space of the cylinder and which is driven by a motor both of which are advantageously carried within the piston.
