Abstract: A resin atomizer unit is provided that is constructed from a variety of ultra high molecular weight (UHMW) plastics. The use of these materials benefits in the construction of a resin atomizer by reducing the resin's tendency to adhere to the critical surfaces during operation. These materials also have the beneficial quality of resisting the abrasive nature of the resin. Another benefit of the use of the materials herein described in the construction of the present invention is that they also lessen its overall weight which makes any maintenance that may be required much easier. Finally, the quick release method of attaching the individual resin atomizers also enhances the ease by which they can be serviced and thereby leads to greater efficiencies in their use.

Abstract: The movement of the intensifier piston in a fuel injector, to control the pressurization of fuel, can be controlled with a flow control valve. The flow control valve provides different flow rates depending upon the direction of flow. In a first direction, flow control valve has a first rate of flow and in the second direction flow control valve allows a second different rate of flow. Typically, this can be applied to a intensifier piston as follows: flow traveling to the intensifier piston, in the first direction, has a first flow rate, allowing the intensifier to move downward and pressurize fuel. When injection is over, and the intensifier piston is vented, the flow control valve allows a second flow rate which is greater than the first flow rate, allowing the intensifier piston to vent quickly and reset for another injection.

More particularly, the invention concerns a needleless syringe provided with a piezoelectric crystal and a triggering device comprising a triggering member and impacting means and, on a triggering device particularly adapted to needleless syringes. The invention is mainly characterized in that the impacting means comprises a latch maintained under elastic stress by being blocked against a stop element and the triggering member is capable of moving the latch to release it, so that it is urged to strike the piezoelectric crystal. Then, the crystal produces an electric arc designed to initiate a pyrotechnic charge whereof the combustion gases will help to expel the active principle contained in the syringe.

Abstract: A unitary over-molded non-clogging system having mechanical breakup capability, a positive shutoff flared wall skirt, having two different overmolded materials forming a laminate combination. The soft flexible face inner portion with a flexible positive shutoff in combination, with mating sealing surface points at two distinct positions, on a conventional actuator body post, forms half of the unitary fitment. A hard portion contour forms the outer half, maintaining registration and retention of the entire overmold fitment within the actuator. This overmold combination fit provides these features without increasing the total amount of parts normally used in conventional spray actuators on pumps and aerosol systems. The actuator can employ a post with or without a mechanical breakup face while the mating surface of the inner soft interfacing portion would compliment it. This type of actuator also can be used as an outlet valve means for pumps, reducing overall cost.
