Abstract: This invention relates to a fluid sealing mechanism for the inside diameter and or the outside diameter of a piston-cylinder arrangement. This device results in zero seal leakage path with low differential seal pressure required using only one piston ring, one ring groove, and very loose dimensional tolerances required on both the ring and related groove. This yields an inexpensive more positive seal for fluid piston-cylinder configuration used in industrial, commercial, and personal use.

Abstract: This invention relates to a fliud sealing mechanism for the inside diameter and/or the outside diameter of a piston-cylinder arrangement. This device results in substantially zero seal leakage path with low differential seal pressure required using only one piston ring, one ring groove, and very loose dimensional tolerances required on both the ring and related groove. This yields an inexpensive more positive seal for fluid piston-cylinder configuration used in industrial, commercial, and personal use. This invention further includes an expander void within the piston wall to permit use of different elastomers.

This invention further relates to a bi-directional sealing assembly wherein one or more of the sealing rings are used in combination with a compresssion spring.

Abstract: This invention relates to a pumping device that is adaptable for commercial and residential use that incorporates a series of pistons and valves that automatically and proportionally injects such fluids as fertilizers, oils, soaps and food syrups into various other liquid mediums.
