  • Patent number: 4496234
    Abstract: A release agent management (RAM) system for use with a heat and pressure fuser. The system is characterized by the use of a simple reciprocating, positive displacement pump for delivering silicone oil to the heated roll of the fuser. The pump is actuated in response to the fuser rolls being engaged and disengaged, such movement being adapted to act against one or the other of a pair of springs which in cooperation with the oil being pumped forms a damper system which is utilized to control the quantity of oil delivered. The springs and oil cause the velocity of the pump's piston to decay with time which results in more oil being pumped initially.
