    摘要: An electric power steering apparatus wherein desired steering assist force can be stably provided by positively precluding actuation of an electric motor while it is rotating in a reverse direction so as to prevent demagnetization of the electric motor. This apparatus includes motor reverse rotation detecting means for detecting whether or not the electric motor is rotating in the reverse direction and motor actuation control means for actuating the electric motor when a condition for actuating the electric motor is fulfilled and on condition that the electric motor is not rotating in the reverse direction.

    摘要: An actuation system particularly for vehicular use in which a pump (10b) draws fluid from a reservoir (10a) to supply one or more first consumers such as a steering valve (50). One or more second consumers such as a clutch actuator (12) are actuated via a solenoid valve (12a) from an accumulator (10c) charged by the pump. The solenoid valve connects the or each second consumer (12) to the accumulator or to the reservoir thus actuating the second consumers. At accumulator pressure levels below a predetermined charge level the flow of fluid to the or each first consumer (50) is restricted to a level sufficient to ensure effective operation of the or each first consumer whilst generating a back pressure sufficient to ensure charging of the accumulator. This flow restriction may be achieved by solenoid valve (12a) or by a separate charging valve (20).

    摘要: In the hydraulically assisted steering system disclosed herein, a hydraulic pump (11) for powering a steering servo (17) is in turn driven either from the vehicle's engine (21), through an electrically controlled clutch (29), or by an electric motor (33) which can drive the pump (11) independently of the vehicle's engine (21). A signal is provided which varies as a function of vehicles's speed and disengagement of the clutch (29) is enabled for vehicle speeds above a predeterminable threshold, thereby to reduce energy consumption. The clutch (29) is engaged, independently of vehicle speed, under high load, e.g. emergency situations.

    摘要: In a flow rate controller for use in a power steering apparatus used in automobiles, etc, a load pressure responding valve (24) equipped with a variable throttle (45) which causes a spring chamber of a flow rate regulating valve to communicate with the low pressure side when the load is light and cutting off the communication of the spring chamber with the lower pressure side in response to the load pressure which rises due to the steering operation is assembled inside a union (17) having a delivery port for sending the working oil the flow rate of which is controlled by the flow rate regulating valve to a control valve. Accordingly, the saving of energy for reducing the flow rate of the working oil to be supplied to the control valve when the load is light is accomplished without substantially changing the pump housing.

    摘要: Die Erfindung betrifft eine Druckmittelversorgung für eine hydropneumatische, niveaugeregelte Achsfederung eines Arbeitsfahrzeuges mit einer von einer Pumpe (11) gespeisten Hydraulikanlage, an die mindestens ein hydraulischer Verbraucher (V1-V3) und Druckspeicher (16,26) bzw. die zugehörigen Zylinderräume oberhalb und unterhalb des Kolbens (5) der für die Niveauregelung des Fahrzeugaufbaus erforderlichen Stellzylinder (1) der hydropneumatischen Achsfederung angeschlossen sind, von denen der obere Zylinderraum (2a) bei Unterschreiten eines für die Einstellung des gewünschten Niveaus benötigten Druckes von der Pumpe der Hydraulikanlage mit Druckmittel aufgefüllt wird, wobei die Pumpe lediglich bei angezeigtem Bedarf an Druckmittel auf Lieferung gesteuert wird. Um bei solchen Hydraulikanlagen, bei denen die Druckmittelversorgung wahlweise mittels einer Konstantpumpe oder einer Load-Sensing-Pumpe erfolgt, einfach aufgebaute herkömmliche Serienventile als Niveauregelventile einsetzen zu können, wird bei Druckmittelbedarf die zu einer Druckmittellieferung durch die Pumpe führende Situation simuliert, wie sie bei der Betätigung eines der Verbraucher gegeben ist.

    摘要: This invention relates to a hydraulic circuit device of a construction vehicle equipped with an excessive pressure oil control circuit (50) in order to reduce a pressure loss when all the operation valves of a work machine are at neutral positions, to reduce power consumption of a hydaulic pump as a whole when a small amount of pressure oil is necessary for a hydraulic circuit of the work machine, to make it possible to effect arbitrarily an unload instruction of the excessive pressure oil and to make it easier to adjust the change of a flow rate at the time of valve switching. This excessive pressure oil control circuit includes a pilot operated unload valve (11) disposed inside an excessive pressure oil supply pipe (51) connected between a hydraulic pump (P1) dedicated to the work machine and a drain pipe (Ct) through a check valve (20) and a pilot pressure change-over valve (12) disposed inside one of pilot pipes (19) for this unload valve.
