<p>An upright housing (2) defines a vertical crushing compartment (5) in which a vertically elongated crusher (8) is slidable. Hydraulic jacks (14) move the crusher downward for collapsing a used oil filter (F). When a predetermined pressure is exceeded, the jacks are vented to a reservoir (43) and return springs (21) move the crusher upward in the compartment.</p> |
