Abstract: A positioning device for a remote control of a heavy duty vehicle or agricultural vehicle includes an elastic element. The elastic element has a fastening portion, configured to be secured to a body of the remote control, and a retaining portion, arranged to cooperate with an actuator of the remote control at a threshold position delimiting a first portion of a displacement trajectory of the actuator, and a second portion of the displacement trajectory, so as to oppose movement of the actuator according to its displacement trajectory along at least one displacement direction upon switching of said threshold position and allow switching at the threshold position in said displacement direction as a result of application of a threshold switching force exerted on the actuator. The threshold switching force is higher than a displacement force necessary for movement of the actuator on the first or second portion of the displacement trajectory.

Abstract: The present invention relates to a pressure regulating device (1), in particular a hand- or foot-operated hydraulic controller for a heavy construction machine, characterised in that it comprises an electrical or electronic means (20) for determining the position of the actuator (18) or the push button (7) including a proportional sensor comprising, on the one hand, a mobile member (21) following the movement of the actuator (18) or a push button (7) and, on the other hand, a contactless means (22) for detecting the position of the mobile member (21) secured to the body (2), as well as an anti-tilting system, a load sensing system for controlling the pressure increase, the idling delivery of the heat engine, or a flow sharing system, comprising such a pressure regulating device (1).

Abstract: The invention relates to a fluid distributor for a heavy-construction machine, comprising a body and a pressure-reducing means which is mounted in said body and comprises a pushrod arranged in a cavity of the body, a plunger being mounted in an oscillating manner. At least one guide in which the pushrod is displaced is immobilized in the cavity, a first seal and a second seal respectively ensuring the hydraulic sealing inside and outside the guide. Said guide comprises at least part of the upper guide and part of the lower guide which are nested inside each other and mutually define a recess facing the pushrod, the first seal being trapped in the recess.
