Abstract: A system is provided for mechanically coupling an electrical supply unit for cordless electrical devices with a charging device, the electrical supply unit includes a housing in which at least one battery that can be recharged by the charging device is located, an associated electrical supply unit, and an associated charging device. At least one guide element is located in the front region of the housing of the electrical supply unit, which engages, for mechanical coupling with the charging device, in a corresponding receiving device on the charging device; the combination of the at least one guide rail and the receiving device functions as a flexible coupling or a slide-in, rear-engagement seat.

Abstract: The invention relates to a hand-held machine tool arrangement, particularly a hand-held circular saw arrangement, a surface milling cutter, or a saber saw arrangement, or the like, having a hand-held machine tool and at least one guide rail which can be seated or clamped to a workpiece to be processed, and having a longitudinal guide for a longitudinal displacement of the hand-held machine tool on the guide rail. It is proposed that the guide rail (1) has at least one recess open to the edge, in which there is a ribbing (20).

Abstract: A system for electrically coupling an electrical supply unit for cordless electrical devices, hand-held power tools in particular, with a charging device, with the electrical supply unit is located in a housing in which at least one rechargeable battery that can be recharged using the charging device is located, and the electrical supply unit and the charging device each have at least a first and a second contact element, wherein the first and second contact elements of the electrical supply unit interact with the first and second contact elements of the charging device such that the charging procedure takes place only when the electrical supply unit is in a defined end position in the charging device.

Abstract: A connecting device (20) for connecting a connection hose or connection tube to a receiving device includes a tubular connection neck (2), an actuating sleeve (28), and a support sleeve (38). The receiving device, to which the connecting device (20) can be connected, includes at least one detent element, which is actuatable by means of at least one actuating element mounted on the receiving device. The connection neck (2) is connectable to the connection hose or connection tube and has a detent lug (20) or detent groove, which can be brought into engagement with the detent element of the receiving device. The actuating sleeve (28) serves to actuate the actuating element of the receiving device. The support sleeve (38) is braced on the receiving device and is axially displaceable relative to the actuating sleeve (28), prestressing a first spring (44).

Abstract: A fuel injection system includes a substantial integration of various components, the fuel injection system including at least one fuel injector and at least one intake manifold, as well as a fuel supply channel, which are all surrounded by a plastic sheathing. The full integration of the fuel injectors into an induction pipe component made of plastic leads to the reduction or elimination of both electrical and hydraulic interfaces. Thus, only a compact component remains that is very simple to attach to a cylinder head of an internal combustion engine. Means for electrically contacting the fuel injectors (1), such as connector sockets, are also fully integrated in the plastic sheathing. This fuel injection system is especially suited for use in mixture-compressing internal combustion engines having externally supplied ignition.
