Abstract: A system for controlling and safeguarding the dispensing of fluids used in servicing centers is provided. The system is devised to provide lubricants to motor vehicles and includes a programmable system that comprises means to activate and deactivate a plurality of fluid dispensing pumps including a shut down of pump feeding air pressure to prevent fluid spills and to preclude the theft or dispensing of fluids at unauthorized times such as at times outside normal servicing hours. The invention also affords improved central proprietors of servicing facilities to set and monitor operable pump periods and includes an automatic shut down, until reactivated by a master key, of pump functions at a specified time of day.

Abstract: A readily portable self-contained, pre-pressurized lubricating fluid dispenser is provided. The tank contains an internal impermeable flexible membrane that isolates the working fluid to be dispensed from the pressurizing delivery fluid, e.g., compressed air, which dispenses the servicing fluid under pressure. The dispenser that can be readily pre-loaded with deliverable servicing fluid, such as motor vehicle lubricant. The tank supplied with or without the servicing fluid is provided with pre-pressurized gas as a permanent sealed fixture with the tank to provide a fully self-contained portable servicing tool. The working fluid is readily replenishable when exhausted. The flexible membrane isolates the working replenishable servicing fluid from the pressurized gas. The unit may be secured to a wall or mobile attachment to a convenient location for periodic scheduled servicing and may comprise a wheeled supporting carriage or a back-pack configuration for optimum versatility.
