ROTARY DEVICE
Document Type and Number:
Japanese Patent JPS5431812
Kind Code:
A
Abstract:
A rotary mechanism including a housing defining an operating chamber having a wall, a shaft journalled in the housing and having an eccentric within the chamber, a rotor within the chamber and journalled on the eccentric, and at least one seal carried by the rotor and slidably engaging the wall. A seal lubricating system is provided and includes an aperture in the wall along with a conduit for directing lubricant to the aperture. A plug partially closes the aperture and has a higher coefficient of thermal expansion than the housing, with the result that an oil-emitting gap is provided and its area changes proportional to temperature, and, thus, oil viscosity, to meter the proper amount of oil for seal lubrication irrespective of temperature.
