摘要： The present invention relates to a hydraulic system control unit, a hydraulic system and a working machine for controlling a hydraulic system adapted to perform at least one hydraulic work function in a working machine. The hydraulic system performs the hydraulic control function in accordance with an operation signal determined by a hydraulic system control unit. In a first step (30) the control unit receives an operator control input associated to said work function. The method is particularly characterized in a second step where the control unit receives (31) a load input indicative of a load associated to the work function. Moreover, in a third step the control unit determines (32) the operation signal in response to the operator control input and the load input.

摘要： A precision servo control system for a pneumatic actuator has a piston (5) positionable over a stroke of the pneumatic actuator (2) using a supply of pressurized gas. A brake (52) and a sensor system (44) are connected to the actuator (2) and to the servo control system. The servo control system operates to initiate the forward thrust from the pressurized gas to move the piston (5) along the stroke. When a braking point along the stroke is determined, the servo control system initiates a reverse thrust from the pressurized gas while maintaining the forward thrust and simultaneously begins to selectively apply the brake (52) to stop the piston within a predetermined tolerance of a desired stopping position. The precision servo control system is easily programmable in a manner similar to that of a control system for electrical actuators. The precision servo control system can maintain the predetermined tolerance even under changing loads, long stroke lengths or vertically oriented stroke directions. The precision control servo system preferably utilizes simple directional valves, instead of complex and expensive servo valves, to regulate the pressurized gas. The precision servo control system achieves positional accuracy to a predetermined tolerance that is a fixed value, regardless of the stroke length.

摘要： The present invention is a vehicular power steering system having an 'open-center' control valve (10) that has substantially zero hydraulic flow gain at zero input deflection angle with minimal control orifice area. A valving sub-assembly is used which functions to rapidly restore hydraulic gain at relatively small input deflection angles. The valving arrangement includes small transverse leakage slots (40', 54') formed in a valve spool that are in fluid communication with either input or return flow distribution slots. The leakage slots are configured to form parasitic flow orifices which fluidically interconnect the output slots (32a, 32b) formed in the valve sleeve and which communicate with the fluid chambers formed on opposite sides of a piston in power cylinder (18). Accordingly, a selectively variable leakage path is provided across the power cylinder. The parasitic flow orifices may have uniform and/or non-uniform areas for customizing performance characteristics.

摘要： A directional valve for controlling an actuator by means of pressurized medium, the directional valve comprising: a spool (4) fitted to move axially inside the directional valve; a first position of the spool (4), in which the spool tends to be set; and a second position of the spool (4), to which the spool can be moved by a pilot control force. In addition to the functions of a directional valve, the directional valve comprises a metering orifice (7) placed in the pressure port (P) or in the first work port (A) or in the second work port (B) or in the tank port (T), and across which a pressure difference is effective. The spool (4) further comprises a second position, to which the spool can be moved by a pilot control force. When the spool (4) is in at least the second position, the directional valve is fitted to generate a compensating force proportional to said pressure difference, to move the spool (4) to compensate for the flow.

摘要： A machine for transferring a payload from one location to another. The machine includes a chassis, a linkage having a first end pivotally attached to the chassis at a first pivot point, and a bucket pivotally attached to a second end of the linkage at a second pivot point and rotatable about the second pivot point from a first position where gravity resists rotation of the bucket to a second position where gravity assists rotation of the bucket. The machine also includes a tilt actuator for rotating the bucket about the pivot point and one or more sensors for providing physical data of the bucket. A processor of the machine receives the physical data, determines from the physical data an equilibrium position of the bucket between the first position and second position, determines a location of the center of gravity of the bucket with payload from the physical data and the equilibrium position, and estimates the weight of the payload based on the physical data and the location of the center of gravity.

摘要： Disclosed is a pneumatic actuator movement indicator comprising a housing adapted to be connected in series between a pneumatic actuator and a source of pressurized fluid for the actuator, and an indicator located in, and having an equilibrium position in, the housing. The housing, includes a first chamber for placing the housing in fluid communication with said actuator at a pressure P1, and a second chamber for placing the housing in fluid communication with said source of pressurized fluid at a pressure P2. The indicator is movable in the housing in response to a difference between Pl and P2. Movement of the pneumatic actuator produces a difference between P1 and P2; and in response to this difference, the indicator moves away from its equilibrium position, indicating the movement of the pneumatic actuator.

摘要： The apparatus (10) is an oscillator for a showerhead (31) to keep the forming fabric of a papermaking machine clean and open. A hydraulic cylinder (12) is formed with a piston cup assembly (32) dividing the cylinder into first and second fluid chambers (36, 38). The piston cup assembly is coupled to a magnet (30) and a driveshaft (24), the driveshaft being coupled, in turn, to the showerhead to be oscillated. A four-way valve (48) is used to direct fluid from a pressurized external source alternately into the first and second fluid chambers thereby causing reciprocation of the driveshaft. The position of the magnet, and hence the driveshaft and showerhead, is monitored by a transducer (44) which sends position and rate signals to a microprocessor-based controller (46). The microprocessor-based controller sends a signal to the four-way valve to direct which of the first and second fluid chambers receives fluid from the pressurized source in order to achieve the desired parameters of reciprocation. Additionally, the microprocessor-based controller provides an alarm signal should the driveshaft rate drop below a preset value.
