  • Method for controlling oil in a press
    Patent number: 5791655
    Abstract: A dynamic oil control mechanism for a press including a vacuum inducing ejector or jet-pump to vacuum oil leaking from about an oil seal. The oil seal is located around the drive piston on the press slide to prevent oil migration from the press crown to the die area or slide of the press. A drain port is located about the housing in which the drive piston reciprocates. The ejector maintains a low pressure area within the drain port to pull oil leaking from the seal into the drain port and away from the drive piston. The vacuumed oil is then transferred to an oil reservoir.
    Type: Grant
    Filed: September 5, 1997
    Date of Patent: August 11, 1998
