NON-PULSATING, NON-THROTTLING, VENTED PUMPING SYSTEM FOR CONTINUOUSLY DISPENSING PRODUCT ABSTRACT OF THE DISCLOSURE A non-pulsating, non-throttling, vented pumping system is disclosed for continuously dispensing product from a container in a relatively non-pulsating stream or spray. The pumping system includes a pump for withdrawing product from a container and for pressurizing the product, a storage compartment for storing the product under pressure, an accumulator piston in the storage com- partment acting under bias to maintain the pressure on the product, an outlet passage opened and closed by the accumulator piston, and a restricted orifice at the outlet passage through which the pro- duct is dispensed as a stream or spray. The restricted orifice allows only a portion of the product pressurized by the pump to escape during the pressure stroke of the pump, and the remainder of the product is stored in the product storage compartment to be released for maintaining the spray or stream when the pressurizing pump is acting on its intake stroke. The accumulator piston shuts off the outlet passage when the pump is at rest in a manner such that the pump is non-throttling. The container is vented to the atmosphere through the pump. The pressurizing pump's actuator has a relatively short stroke and so can be pumped rapidly such that the stream or spray need not be maintained by the accumula- tor piston for a long time on a given intake stroke.
