摘要： A method and a device for centrolling, during slow acceleration of the working movement of a hydraulic cylinder and/or motor, a flow delivered under pressure from a pump system (100), especially an adjustable pump with a combined constant power and constant pressure control, so as to obtain a practically loss-free acceleration in that no excess flow is supplied to the working cylinder or working cylinder or motor.
This is achieved during the acceleration process by operating in different ways, either only the pressure control level of the pump system (100) by setting means (702), or simultaneously also the setting of the beginning of the power control of the pump system (100) by setting means (701).
Said setting means (701, 702) consist e.g. of a piston and cylinder assembly or a proportional magnet the force of which generally acts on a preloaded adjustment spring.
The setting of the pressure control level or the beginning of the power control during the acceleration of the working movement of a hydraulic motor (251) is brought about, e.g. by having the servo (pilot) pressure (control signal) from the remote control system (300) by means of which the hydraulic motor is operated to directly act on both ore one of the setting means (701, 702).

摘要： A control lever (13, 34) is distinctly movable in different planes for actuation of different control means (15-18) in that it has, adjacent the control lever housing (10), a plate (37) provided with a number of bevelled flat edges (50, 51) corresponding to the number of planes in which the control lever is movable, the plate (37) being tiltable on said flat edges by means of said lever on which it is also movable. A spring (46) is provided between the plate (37) and a fixed abutment (41) on the lever for holding said lever (13) in engagement with a seat (28) and for urging said plate (37) against a planar portion of the housing (10). When the lever (13, 34) is moved in a given direction, the plate (37) is tilted about the edge (50, 51) against the action of the spring (46), any risk of the lever moving in another undesired plane being effectively eliminated.

摘要： An apparatus for restricting the velocity of movement of the piston (13) in a servo-controlled hydraulic working cylinder (12), when the piston approaches at least its one end position in the cylinder, by means of a hydraulic sensor (20, 21) secured on one of the machine parts which are shifted with respect to each other by means of the hydraulic working cylinder (12). The hydraulic sensor is coupled via a non-return valve (24) to the servo-circuit. When the piston (13) of the hydraulic working cylinder (12) approaches its end position in the cylinder, the hydraulic sensor (20, 21) ist actuated by the second of the above-mentioned machine parts, whereby a pressure exceeding the servo-pressure is established in the cylinder of the hydraulic sensor (20, 21). A valve (23) senses the pressure difference between the servo-pressure and the pressure established by means of the hydraulic sensor (20, 21) and throttles the servo-flow to the main valve (14) of the hydraulic working cylinder (12), the main valve thereby throttling the pressure medium supply to the hydraulic working cylinder (12).
摘要翻译：一种用于通过固定地安装在其中一个机器部件上的液压传感器来限制伺服控制的操作液压单元的活塞的运动速度，当活塞至少接近气缸中的一个端部位置时，该液压传感器是通过操作液压单元相对于彼此移动，并且通过止回阀的中间联接到伺服电路。当操作液压单元的活塞接近其在气缸中的终端位置时，液压传感器由上述第二机械部件致动，由此在液压传感器的气缸中建立超过伺服压力的压力。阀门感测到伺服压力和通过液压传感器建立的压力之间的压力差，并将伺服流量节流到主阀的操作液压单元的主阀，从而将压力介质供给节流到操作液压单元。

摘要： To limit the power output of a hydraulic assembly consisting of hydraulic motors (10), hydraulic pumps (11) driving said motors (10), a pump driving motor (13) and control means (14) for controlling the hydraulic flow to said hydraulic motors (10), a controller (16) is provided which is supplied with an input signal (D) from a subtractor (17) which in turn is supplied with signals (R and A) from a reference value setting device and an actual value setting device (20), respectively, the actual value setting device sensing the speed of the driving motor (13). The output signal (K) of the controller (16) is applied to all of the control means (14) and is multiplied in each control means by a signal proportional to the setting of said control means, in order to obtain the flow control signal.

摘要： Method and device for reducing the piston speed in a piston and cylinder assembly (1), as the piston approaches the end position. The piston end position is sensed, and a signal is generated for starting the end position dampening. Dampening is effected in two steps. In the first step (14), a time delay is provided and in the next step (15), the actual braking (retardation) of the piston is effected. The invention also comprises an electronic braking device comprising a dampening activation unit (13) which is connected to transducers (6), a braking delay unit (14) connected to said unit (13) and also to the control lever (5) at issue and a reference signal source, as well as a braking unit (15) connected to said delay unit (14) and adapted, upon activation, to provide a signal (U) to a setting system (3) for controlling the supply of pressure fluid to said piston and cylinder assembly (1).

摘要： To reduce the piston rate in a piston and cylinder assembly (11) as the piston approaches the end positions, a signal transmitter (18) is provided for sensing the position of a part driven by means of the piston and cylinder assembly.
The signal of the signal transmitter (18) is applied to a control unit (24) in which it is compared with a signal (S) from an actuator means (22).
The comparison of signals is so exploited that if it is established by this comparison that the piston is not in the areas of the end positions alternatively, is in these areas but is activated by the actuator means (22) to move away therefrom, the signal (S) is not acted upon by the actuator means (22) whereas ifthe piston is in these areas and approaches the end pistons the hydraulic fluid supply to the piston and cylinder assembly (11) is continuously reduced.
