    Abstract: The pressure dependent release device has a tubular rachet carrier, which can move axially in a housing bore and holds one or more catch blocks. The catches are pressed radially outwards in locking recesses of the housing bore by a cam body tensioned to the catch position by a second spring and is arranged in an axial bore of the ratchet carrier. A pre-control valve, coaxial with the ratchet carrier is under the tension of a first spring and on its opening, the control pressure medium acts on a piston which moves the cam against the action of the second spring. There are radial recesses directly behind the piston to deflect the control medium. A sealing point is arranged between the recesses and a space which accepts the first spring. The cam body has a pick-up on one side which presses through a hollow screw which forms the spring thrust bearing.

    Abstract: The hydraulic tractor brakes have separate master brake pistons and master control valve through which the rear wheels are separately braked, as well as any trailer brakes. Servo brake fluid is supplied by a pump to a distribution valve through which any hydraulically powered accessory can be supplied when the brakes are open. The master cylinders, when operated separately, operate on a balancing piston in the control valve to block the fluid flow to one of the rear wheels. In the event of servo failure a balancing control valve prevents the separate operation of the rear brakes and uses the full manual effort on the mater brake cylinders for manual braking of both rear wheels. The master brake cylinders and the master control valve can be mounted in separate locations for a compact layout.

    Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce the noise level of a machine by means of the hard fastening of a stator between housing half parts and to improve the engagement of a stator bedding iron core between the housing half parts within the range a fastening screw. SOLUTION: Individual bedding boards 11a of the stator bedding iron core 11, which are fastened between contact faces 31 provided for the housing half parts 13 and 14 and a centering face, are mutually connected by at least two welding seams 32 which are arranged symmetrically on the both sides of, with respect to a fastening screw 15 providing small intervals.

    Abstract: An electromechanical dynamometer (10) for determining the force acting on a movable, force-transmitting element (11) of a machine is proposed, in which a flexible, tubular bolt (16) in a cavity (17) has a rigid measuring rod (19), firmly clamped at one end to one bolt end (26), and a sensor (21) inserted at the other bolt end (27). The free end (23, 24) of the measuring rod (19), as well three poles (33 to 35) of the inductively operating sensor (21) are situated on both sides of a plane (36) which extends radially relative to the longitudinal axis of the bolt (16). Oppositely directed variations of the air gaps (37, 38), formed between the end (24) of the measuring rod and the outer poles (33, 35), due to the shifting, free end (24) during deflection of the bolt (16) under the effect of force produce voltage signals at the sensor terminal (42) whose magnitude is proportional to the magnitude of the force (15) to be measured. The dynamometer can be extended for measuring forces in two different planes, and permits manifold types of regulation of add-on units in the case of electrohydraulic lifting gear control devices of tractors.
