Abstract: The description relates to a safety circuit for the alternating running of consumers, e.g. gear components of a power shift gear, and a proportional valve for such a safety circuit, in which the proportional valve can preferably be electrically adjusted. The proportional valve has a switch output to which one of the consumers is connected, while a proportional output of the proportional valve is taken to another consumer. It is possible by the corresponding control of the proportional magnet to switch over gently from one consumer to another without the need for a hydraulic device to modulate the switching process.

Abstract: The invention concerns a hydraulic device for controlling the hydraulic-fluid flow to and from a single-acting cylinder (3) on which a load (4) acts. Located between a pump (1) and the cylinder (3) is a controlled valve array (5) which, together with a controlled on-off valve (9) which in one position allows hydraulic fluid to pass back into the reservoir (2), controls the flow of hydraulic fluid to and from the cylinder (3). In order to be able to lift the piston slowly and at constant speed in the cylinder (3), independently of the load (4) acting on the piston, the invention calls for a throttle (6) and a non-return valve (7) to be connected in series, by-passing the valve array (5). A pressure regulator (10) maintains the pressure difference through the throttle (6) constant and feeds the fluid not required to maintain the pressure difference through the throttle (6) back to the reservoir (2). When the load (4) is lifted slowly, the valve array (5) is switched into a position in which the flow of hydraulic fluid to the cylinder (3) is blocked, and the cut-off valve (9) blocks the connection between the throttle (6) and the reservoir (2). The invention is particularly suitable for use in controlling the lifting gear of a mobile machine such as a stacker truck or an agricultural machine.

Abstract: Disclosed is a valve assembly (8, 10) for the control of a comsumer (1) having two directions of operation, the valve assembly comprising a proportionally acting directional-control valve (12) connected in series with an on/off valve (42) which together control the supply of hydraulic fluid through the outlet of the directional-control valve (12), while a feedback line from the consumer (1) runs through the on/off valve (42) to a hydraulic-fluid reservoir.

Abstract: The invention concerns a hydraulic valve used in particular to ease a spring-loaded brake and which has a housing (10) and an actuator element (40) mounted on the housing and adjustable in two opposite directions. The valve also has an obturator element (14) fitted so that it can move within the housing, a control spring (26) fitted between a mobile support element (27) and the obturator element and a reset spring (25) fitted between the housing and a support element (28). The force in the reset spring can be increased by moving the actuator element in one direction and, when the actuator element moves back in the opposite direction, the reset spring moves the control-spring support element in the direction which increases the force in the control spring. In order to keep the force necessary to operate the brakes low, mechanical force-magnification means (48, 51) are fitted to act between the reset and control springs. The resetting force which the reset spring is required to produce is thus relatively small, thus also making it possible to keep the force necessary to compress the reset spring small.

Abstract: A directional control valve (4) has snap-locking means (2) for retaining the slide (6) of the directional control valve in at least one switching position. The snap-locking means have a snap-locking part (8) with a snap-locking piston that allows an engagement part (12) to engage and lock the slide of the directional control valve. Kick-out means (16) disengage the engagement part when a predetermined control pressure is exceeded. The kick-out means triggering force may be adjusted by means of setting means (22) that act on a kick-out spring (20). Switching means (24) that allow the kick-out function to be switched off independently of the setting of the setting means are associated to the directional control valve in order to prevent disengagement independently of the initial stress of the kick-out spring.

Abstract: In order to reduce overshooting of the controlled variable upon rapid changes of the reference variable (w) in a closed-loop control circuit consisting of a PID controller with parallel proportional component (3), integral component (6, 7) and differential component (4, 5), and a controlled system with quasi-integral behavior, the time derivative of the actual value of the controlled variable (y) is fed to the integral component of the PID controller with a negative sign. The PID controller is particularly suitable for automatic control of the r.p.m. of hydraulic secondary units, and for automatic pressure control with hydraulic variable-displacement pumps, and can be implemented simply as a digital controller.

Abstract: The valve unit proposed has a housing (10) and at least one pump connection point (P), a reservoir connection point (T) and a consumer connection point (A) plus a pressure limiting valve (20) and a control valve (18) incorporated in the same assembly, the two valves (18, 20) being connected in parallel to each other between the pump connection point (P) and the reservoir connection point (T). The valve unit proposed enables hydraulic circuits for the protection of hydraulic pumps and/or for the balanced starting of a hydraulic pump, as well as for the reduction of the pressure at a hydraulic consumer, to be designed to fit in a very small space. In the event of damage, the valve unit can be rapidly replaced by a new one, thus avoiding long consumer down times.

Abstract: A simply-designed, multi-purpose transport module with which heavy loads can be moved over the ground has the following features: a frame, on which the load is laid, is positioned on the floor. A support is positioned on the floor. The ground loading pressure of the frame, on an increase of the ground pressure loading of the support, and the ground pressure loading of the support, on an increase of the ground pressure loading of the frame, can be reduced to below the unloaded weight through an actuator of the frame or of the support. The frame and the support have a first pair of inclined paths through which the frame can be supported on the support and the frame is displaceable horizontally with respect to the support on achieving a sufficient reduction of its ground pressure loading. The frame and the support have a second pair of inclined paths through which the support can be supported on the frame and the support is displaceable horizontally with respect to the frame on achieving a sufficient reduction of its ground pressure loading. A load can be moved forward in a step-wise manner with such a transport module.
