    摘要: A device for controlling the connection between a pressure medium source and a medium supply container is provided in a pressure medium operated system. The device includes a control valve with a housing formed with a longitudinal bore, in which a valve member is axially displaced between two end positions by pressure of the pressure medium. The valve member includes a piston and a seat portion facing a valve seat formed in the valve housing. The piston is of the diameter larger than that of the valve seat. A bore connected to the medium supply container is provided in the valve housing which is controlled by displacement of the piston.

    摘要: A force measuring procedure and a force measuring apparatus are used to control the power hoist of an agricultural tractor. The force measuring procedure operates in such a manner that the relative displacement of a point on an elastic system is detected by at least one Hall sensor disposed on either the elastic system or on the fixed frame with the Hall sensor being located in a magnetic field with a predeterminable magnetic flux. For this the force measuring apparatus has a flex rod attached to at least one of a pair of lower hitches which indicates the bending moment, and the Hall sensor is mounted with its detector surface essentially in the primary plane of bending deformation of the flex rod and is connected to the control circuit of the power hoist. The described force measuring procedure and the force measuring apparatus operating with this procedure produce the particular advantage that the mounting of the parts needed for the apparatus becomes extremely simple, with a resulting high degree of measuring precision and operating reliability assured for the apparatus. The force measuring procedure and the force measuring apparatus can thus be used to particular advantage whenever the objective is to continuously monitor the construction elements of a mass produced mechanical system.

    摘要: A hydropneumatic suspension having at least one suspension cylinder (10) and at least one hydraulic accumulator configured as a suspension accumulator (18) has a pilot-actuated valve (20) for opening or blocking a fluid-carrying connection between the suspension cylinder (10) and the suspension accumulator (18). The pilot-actuated valve (20) can be moved into the blocked position by a hydraulic actuating assembly (22). The hydraulic actuating assembly (22) taps the fluid pressure between suspension accumulator (18) and the suspension cylinder (10), and forwards it by a switching valve (24) to an operating side (26) of the pilot-actuated valve (20) through a pilot-actuated line (38). Another proportional valve (50), or such valve connected to the respective associated pilot-actuated line (38), can be between one switching valve (24) and the pilot-actuated valve (20).

    摘要: A suspension device is for at least one drive part (10) that is to be cushioned. The drive part can be connected to an accumulator device (12) by a first valve unit (28) and to a tank connection (46) by a second valve unit (34) to transport fluid. The device is provided with a pressure compensation device (50), which when actuated compares the respective prevailing pressures in the drive part (10) and the accumulator device (12) to generate a common pressure level. This comparison permits the pressure level to be rapidly compensated in advance when the actual suspension is enabled in the form of the accumulator device, in such a way that the suspension pressure employed exactly matches the pressure of the respective drive part in the form of a hydraulic or working cylinder that prevails in the later as a result of the preceding load actuation operations.
