In the open position, the roof structure can be lowered into a folding-top compartment in the region of a tail gate supported via a pivot pin. The tail gate is articulated via its pivot pin, on an auxiliary frame. For its part, the auxiliary frame is supported, via a pivot pin, on the bodywork in the lower vehicle end region.

Abstract: A hard-top vehicle is provided with a roof structure which includes a roof part and a rear-window part connected pivotably thereto. The roof structure is lowered from a closed position, in which it bears in the region of a front windscreen frame and covers the rear-passenger-compartment region, into an open position, towards the tail-end region of the vehicle, via a positive-control device. The positive control device is supported in the tail-end region of the vehicle bodywork and can be pivoted about a tail-end pivot pin fixed to the vehicle, into a folding-top compartment. The positive-control device includes at least one control element which is connected in a rotationally fixed manner to the roof part in the region of a roof pivot pin. In this arrangement, the control element is designed as a linkage which acts on a guide part, in the region of the roof pivot pin, with a guide rod and a main guide rod.

Abstract: In the case of a motor vehicle having a lowerable roof structure, respective roof parts pivoted into an open position, in which they release the rear passenger compartment of the vehicle, can be pivoted at least partially into a folding-top compartment in the tail-end region of the vehicle. In this arrangement, the folding-top compartment region merges directly into a trunk region covered by a tail gate. Provided between the two regions is at least one intermediate wall which can be moved into a closing-off position or open position. The intermediate wall is designed as a roller screen, a folding screen, or the like, which runs in respective lateral guides. In its closed-off position, the intermediate wall extends rearwards forming an upper boundary of the trunk region.

Abstract: A fuel injection pump designed to deliver an amount of fuel divided into a pilot and a main injection volume, including a surface of a pump plunger which is guided within a pump cylinder, apart from two recesses limited by an inclined control edge, a first horizontal control edge is formed by a frontal shoulder; and on a side opposite the shoulder, it has a fully enclosed transverse groove with a second and third control edge. Two control apertures and an annular groove above them in the wall of the pump cylinder effect the control, in conjunction with the aforementioned control edges, of the precisely determinable pilot injection and, after a delivery interval, determined by the difference (b-a) between the width (b) of the transverse groove and the distance of the annular groove to the control aperture, the subsequent main injection.

Abstract: A pressure valve is proposed herein which is built into the injection pump, its valve closing body being guided in a valve carrier, and arranged to open in the supply direction of the fuel, counter to the force of a restoring spring. A check valve is built into the pressure valve, its valve seat carrier being secured to the valve closing body and its movable valve closing member is arranged to open counter to the supply direction of the fuel via a spring supported on the base of the valve closing body. For axially securing the valve seat carrier on the valve closing body, the restoring spring simultaneously engages the valve seat carrier. As a result, the satisfactory functioning of the check valve is assured.

Abstract: A fuel injection pump for internal combustion engines having an equal-pressure relief valve, which has a structure requiring little space when installed and is provided with a fastener element. The equal-pressure relief valve comprises a pressure valve body, onto which a beaker-shaped filler piece protruding into the interior of the pressure valve spring is placed. The structural unit comprising the pressure valve body and the filler piece containing the relief valve is held together, even when the pipe connector fitting or the pressure valve spring is removed, by means of the transit fastener element provided with a fastener ring. The invention is applicable both to single and series fuel injection pumps as well as to distributor injection pumps, particularly when space for installation is restricted.

Abstract: The support of a relief valve in a constant pressure relief valve of the fuel injection pump comprises a bolt and two openings for receiving it in the sheath-like wall of the movable valve closing body. The openings are embodied by a bore drilled through the wall of the valve closing body at right angles to the longitudinal axis of the valve closing body. The bolt receives a spring plate of a spring of the relief valve in a depression and is thereby positioned and secured.

Abstract: Cylindrical sleeve having a top portion of enlarged diameter which includes a control bore and which is clamped by an annular screw against a shoulder of a reception bore in the pump housing. An annular screw has, in a widened bore portion at least partially surrounding the top portion of the cylindrical sleeve, a pressure shoulder which is recessed relative to the end face of the annular screw presented to the suction chamber and which transmits the clamping force to the cylindrical sleeve. In a further refinement, the annular screw is provided with an annular extension which surrounds the cylindrical sleeve at a distance therefrom in the region of the control bore and whose inner wall forms a protection against impingement of the jet of fuel emerging from the control bore upon the termination of fuel delivery.
