Abstract: A lighting device for a vehicle steering wheel rim, comprising a holding body comprising at least one internal wall with at least one opening, at least one light source arranged to emit light, a diffuser arranged to diffuse the light coming from the at least one light source towards the vehicle occupant, a light guide arranged to guide the light emitted from the at least one light source towards the diffuser, wherein the light guide comprises a light collecting face arranged on a first side of the opening, a light emitting face arranged on a second side of the opening, and the light guide is also engaged with the diffuser to shape it with a predetermined size.

Abstract: An automatically actuated shunt valve system opens and closes a passage between two chambers of a powered element operated by a power source. The shunt valve system includes a coupler connecting the powered element with the power source through two mating coupling elements. One of the coupling elements includes a valve contact and the other includes a shunt valve assembly. The shunt valve assembly includes a valve chamber connected with both chambers of the powered element, a valve element opening or closing a flow path between the conduits, and a shaft for moving the valve element. The shaft engages the valve contact to move the valve element to close the flow path when the coupling elements are mated together, and moves the valve element to open the flow path when the shaft disengages from the valve contact as the coupling elements are disconnected from one another.

Abstract: A front loader arrangement includes a hydraulically sprung lift cylinder arrangement coupled between opposite loader arm sides and respectively mounting masts. In order to permit the masts to pivot freely about their pivotal connections with the loader arm sides to aid the coupling of the masts to respective mounting frames fixed to a carrying vehicle, the hydraulic system in which the lift cylinder arrangement is incorporated includes a device, including a shut-off valve and an accumulator arrangement for establishing a float condition in the lift cylinder arrangement after a source of hydraulic fluid and associated control valve is decoupled by separating a hydraulic quick coupler.

Abstract: A front loader arrangement (12) with a mounting frame (16) and mounting mast (18) is proposed, wherein the mounting mast (18) can be coupled to the mounting frame (16) and can be decoupled therefrom. Furthermore, a loader arm (20) is connected to the mounting mast (18) for being pivoted vertically by a hydraulic cylinder (24) extending between the loader arm (20) and the mounting mast (18). In order to facilitate coupling of the mounting mast (18) to the mounting frame (16), it is proposed that a hydraulic system (85) be coupled to the hydraulic cylinder working chamber(s) (90, 96) and include adjusting means by which the hydraulic cylinder (24) can be brought into a floating position when the hydraulic fluid supply is decoupled from the hydraulic system (85).
