Abstract:
A reciprocal type of pump or motor structure wherein a piston (21) has a linear function actuated by a pair of coils (30, 31) energized alternately and in the pump structure a check valve (39) in an outlet of the structure which stretches to open said outlet under the impact of expelled fluids and of its own volition retracts to the closed position immediately upon the cessation of fluids being expelled.
Abstract:
Es wird eine Einstempel-Einspritzpumpe für schnelllaufende Brenkraftmaschinen vorgeschlagen, die, bedingt durch ihre kompakte Bauweise und dem guten volumetrischen Wirkungsgrad in Verbindung mit einer hohen Oszillationsfrequenz des Kolbens eine einer Mehrstempel-Einspritzpumpe vergleichbare Fördermenge hat, ohne dass die Drehmomentspitzen beim Antrieb der Einstempel-Einspritzpumpe unzulässig hoch werden.
Abstract:
PROBLEM TO BE SOLVED: To provide an improved adhesive discharge system and a method, including use of a pump of causing an integrated diagnosis used in normal operation, for the purpose of the present invention.SOLUTION: The adhesive discharge system comprises the pump and at least one sensor for detecting the movement of a component of the pump and positioned so as to generate a signal based on the detected movement. The discharge system is also a controller for operating the pump, and comprises the controller for communicating with at least the one sensor so as to collect information on an operation cycle of the pump based on the signal. As a result of it, one or a plurality of diagnostic processing become possible in the controller in operation of the adhesive discharge system. These diagnostic processing can include a leakage amount test on the discharge system, an overspeed detection test on the pump and predictive service life cycle monitoring of the pump or the other constitution member.
