摘要： A fluid pressure operated piston engine apparatus generally includes a piston unit, a valve configured to selectively direct pressurized fluid into the piston unit, a valve shifting mechanism, and a magnetic detent device. The magnetic detent device includes a valve actuating member coupled to a valve element in the valve. The valve actuating member is movable between first and second magnetically held positions respectively holding the valve element in first and second positions. The valve shifting mechanism includes a biasing device operatively connected to a shaft associated with the piston unit. As the shaft approaches the first and second ends of its stroke, the biasing forces are used at least partially overcome magnetic attraction holding the valve actuating member. In this manner, the valve actuating member moves between first and second magnetically held positions to cause the valve element to shift and redirect pressurized fluid into the piston chamber of the piston unit to effect reversal of the direction of travel of the shaft.

摘要： Apparatus for dispensing a liquid includes a manifold (14) having a high pressure passageway (20) adapted to be coupled to a source of the liquid and to deliver the liquid at an elevated pressure to a dispenser. The manifold (14) further includes a low pressure passageway (70) for exhausting pressurized liquid from the high pressure passageway (20). A pressure relief valve (16) is coupled between the high pressure passageway (20) and the low pressure passageway (70). The pressure relief valve (16) has a valve member (40) mounted for movement relative to a valve seat (34). One side of the valve seat (34) defines a high pressure side in communication with the high pressure passageway (20) and another side of the valve seat (34) defines a low pressure side in communication with the low pressure passageway (70). A dynamic seal (66) engages the valve member (40) on the low pressure side and prevents leakage of the liquid from the low pressure side.

摘要： An adhesive dispensing device includes a heater unit (20) for melting adhesive, a fill system communicating with a receiving space for feeding the heater unit, and a reservoir 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 reservoir are minimized in size so that adhesive is not held at elevated temperatures long enough to char or degrade.

摘要： 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).

摘要： 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.
