Abstract: PROBLEM TO BE SOLVED: To solve the problem on a device for reducing pressure in a fluid system that a dynamic seal contained in a pressure relief valve operates on the high pressure side of the fluid pressure system, resulting in increased wear or reduced life, and to allow easy removal, maintenance and/or replacement as required by constructing an assembly integrated with the pressure relief valve and a manifold. SOLUTION: To solve the above problem, a liquid dispensing device has the manifold which has a high pressure passageway adapted to be coupled to a liquid source and deliver the liquid at elevated pressure to a dispenser. The manifold has a low pressure passageway for exhausting pressurized liquid from the high pressure passageway. The pressure relief valve is coupled between the high pressure passageway and the low pressure passageway. The pressure relief valve has a valve member mounted for movement relative to a valve seat, and one side of the valve seat is communicated with the high pressure passageway and another side is communicated with the low pressure passageway. The dynamic seal has contact with the valve member on the low pressure side for preventing the leakage of liquid from the low pressure side. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To improve an adhesive dispenser device and a level sensor for use with different types of hoppers and different types of filling processes.SOLUTION: An adhesive dispensing device 10 includes a heater unit 20 for melting adhesive, a fill system communicating with a receiving space 16 for feeding the heater unit, and a reservoir 22 for receiving melted adhesive from the heater unit. The dispensing device also includes a capacitive level sensor 18 located along a sidewall of the receiving space such that the level of adhesive in the receiving space can be detected by sensing the difference in dielectric capacitance where the adhesive is located compared to where air acts as the dielectric. The size of the driven electrode 100 produces a broader sensing window capable of generating multiple control signals corresponding to different fill levels of adhesive. The receiving space and the reservoir are minimized in size so that adhesive is not held at elevated temperatures long enough to char or degrade.

Abstract: PROBLEM TO BE SOLVED: To provide a reciprocating piston (double-stroke piston) capable of positively continuing operation and maintaining reliability. SOLUTION: This fluid pressure operated piston engine apparatus includes a piston unit, a valve configured to selectively direct a pressurized fluid into the piston unit, a valve shifting mechanism, a magnetic detent device, and a valve actuating member. The valve actuating member moves between first and second magnetically-held positions to cause a valve element to shift and redirect the pressurized fluid into a piston chamber of the piston unit to effect the reversal of the direction of the travel of a shaft member.

Abstract: An apparatus for spraying molten thermoplastic adhesive in which the outside of a solid stream of adhesive ejected from a nozzle is impacted by atomizing air to form adhesive droplets and the droplets are then directed by pattern-shaping air into a predetermined area of a substrate. The flow rate and velocity of the atomizing air and pattern-shaping air is independently controlled by separate regulating valves to permit variation of the size of the adhesive droplets formed and the width of the pattern of droplets deposited on a substrate. Control valves are provided to sequence the flow of adhesive discharged from the nozzle with the flow of atomizing and pattern-shaping air such that the flow of atomizing and pattern-shaping air is initiated before the flow of adhesive from the nozzle begins and after the flow of adhesive therefrom is terminated.

Abstract: A fluid pressure operated piston engine assembly (10), such as a pump assembly, including a fluid pressure operated piston engine (12) and a fluid valve (14) for coupling fluid under pressure to alternative portions of the piston chamber of the piston engine. The fluid valve (14) includes a valve spool (26) which is translated to effect the alternative modes of coupling pressurized fluid to the piston chamber (18). The translation is accomplished by a shifter assembly (80) having a shifter rod (82) attached to the valve spool (26). The shifter rod (82) includes a pair of diametrically opposed magnets (100,108) attached thereto. A fork (86) is attached to the piston engine drive shaft (22) at one end and is mounted for limited movement along the shifter rod (82) between the pair of magnets (100,108) of the shifter rod (82). The interaction between the flux generated by a magnet (96) carried by the fork (86) with one of the magnets (100,108) of the shifter rod (82) causes the shifter rod (82), and in turn the valve spool (26), to shift from one position to another, thereby re-directing the flow of fluid to the piston chamber (18) to effect the reversal of direction of travel of the piston (20) and its associated drive shaft (22).
