ABSTRACT:
An oil filter crusher includes a housing within which a piston assembly is mounted for reciprocating movement. The crusher is connectable to an external source of pressurized air, and an air valve is located in the interior of the housing for controlling supply of pressurized air to the piston assembly. A door is mounted to the housing for movement between open and closed positions. An actuator arrangement is provided between the door and the air valve, for actuating the air valve upon closing of the door to initiate a crushing stroke of the piston assembly. A locking arrangement is provided between the piston assembly and the door, to prevent the door from being moved to its open position during the crushing stroke of the piston assembly. A shut-off arrangement provided on the piston assembly causes movement of the door away from its closed position during completion of the crushing stroke of the piston assembly, to cause the actuator arrangement to cut off pressurized air supply through the air valve to the piston head. Springs mounted to the piston assembly then return the piston assembly to an upper position in preparation for a subsequent crushing operation.
