Patent number: 4537423Abstract: Plate-like ballast weights attached by noses to a support or carrier element located at the front of an agricultural prime mover. The nose of each individual ballast weight is spaced from the rest of the ballast weight by such an amount that the latter can be hung by the nose on the support or carrier element in a hanging-in or attaching position, and can subsequently be pivoted into its end position with the nose on a slope or inclination of the support or carrier element. A projection in the lower region of the ballast weight catches in a recess in the end position of the support or carrier element. The ballast weights can be secured in this end position by an arresting arrangement in the region of the noses thereof.Type: GrantFiled: August 10, 1982Date of Patent: August 27, 1985Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventors: Walter Nau, Jes Carstensen

Patent number: 4527622Abstract: A ring-shaped recuperative heat exchanger, for instance for small gas turbines, having axial channels for the exhaust gas system with increasing channel width over the diameter thereof, and having guide plates in a wavy shape for increasing the surface thereof. In an embodiment as a parallel flow or counterflow heat exchanger, the air supply channels are constructed in an identical or similar manner, with a separation of the channels from each other being effected by radially disposed intermediate plates. In a construction as a crossflow heat exchanger, the air conveying channels are formed by wavy shaped guide plates having constant wave height and wave width in a radial alignment. The separation between hot gas and air conveying channels is again effected by additional approximately radially disposed intermediate plates.Type: GrantFiled: August 5, 1982Date of Patent: July 9, 1985Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventor: Thomas Weber

Patent number: 4455973Abstract: A cylinder head, for a water cooled internal combustion engine, which reduces the thermal stresses. The gas-changing channels and the oil-return channels are located on one side. A main water overflow, in conjunction with an oppositely located auxiliary water overflow, makes possible a precise or directed flow along the valve land portion and around the turbulence chamber or the injection nozzle channel, whereby the flow is kept along the cylinder head bottom by a roof-shaped wall on the side remote from the cylinder block. The strength of the cylinder head is increased, and the oil removal is improved, by associating an oil-return channel with each cylinder. Specially shaped cylinder head screw channels increase the compression or pressure against the combustion chamber walls and effect a more uniform pressure distribution. A more favorable sealing behavior is attained by compensation or expansion curvatures in the cylinder head cover plate.Type: GrantFiled: March 7, 1983Date of Patent: June 26, 1984Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventors: Hans Stadler, Lothar Bauer, Wolfgang Strusch

Patent number: 4453511Abstract: An arrangement for lubricating, especially for internal combustion engines is disclosed. The circuit of the arrangement is fed with the lubricating medium, e.g. oil, by way of a pump which delivers oil from a source, as required through an oil cooler and a filter, to bearings of the engine which require lubrication, and to more remote bearings, such as are used in auxiliary equipment, e.g. off-gas turbo-superchargers. In the main pressure conduit, relatively close to the pump, there is provided a flow control device with a direct conduit being provided to communicate the pump with the more remote bearings. The direct conduit is connected to the circuit between the pump and the flow control device. As required, an oil filter can be arranged in the direct conduit.Type: GrantFiled: March 19, 1982Date of Patent: June 12, 1984Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventor: Heinz Pluequet

Patent number: 4453510Abstract: A reciprocating piston internal combustion engine having an intake air system, an exhaust gas system, and an injection pump. To lubricate the injection pump, the latter can communicate with the lubricating-oil system of the internal combustion engine; the injection pump conveys a fuel having a low boiling point. A vaporizer is provided, the input side of which can communicate with the lubricating-oil return line of the injection pump, and the output side of which can communicate with the lubricating-oil system of the internal combustion engine and with the intake air system. The vaporizer serves for purifying the lubricating oil of fuel constituents which have a low boiling point and which contaminated the lubricating oil as a result of unavoidable leakages within the injection pump.Type: GrantFiled: September 6, 1983Date of Patent: June 12, 1984Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventor: Heinz Kupper

Patent number: 4440337Abstract: A method of producing similar deep-drawn parts for double-walled structural parts having uniformly spaced walls and edge welding. During every deep-drawing procedure, a respective planar outer plate, which is placed upon the lower part of the tool, as is a filler plate, as well as a preformed or preshaped inner plate, which is placed over the tool punch, are shaped in common, whereby the preformed inner plate and the outer plate receive their final form or shape, and the filler plate is deformed into a preshaped inner plate for a subsequent deep-drawing procedure. The tool for carrying out this method is characterized in that the smallest spacing between the tool punch and the lower part of the tool corresponds to the entire thickness of the two inner plates and one outer plate.Type: GrantFiled: October 8, 1981Date of Patent: April 3, 1984Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventor: Rolf Eckert

Patent number: 4432704Abstract: A mechanical speed regulator for an injection pump which has centrifugal weights on its drive shaft. The centrifugal weights shift the regulator or control pin axially against the force of a starting supplementary feed spring, whereby in operation the control pin additionally is balanced or equalized with a control spring. The control spring is arranged at one end and the control pin is arranged at another end of a beam arranged to swing freely. A suspension of the beam is shiftable in the longitudinal direction of the beam. The suspension of the beam is arranged and embodied practically free of friction, for instance point journalling being provided therewith. The control pin at its free end provides a knife edge which fits into a correspondingly embodied depression or recess in the beam, and the beam has a conical tip elevation for receiving the control spring. An adjustable abutment is provided in the form of a set screw on the beam in the axial extension of the control spring.Type: GrantFiled: December 3, 1981Date of Patent: February 21, 1984Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventor: Max Matzen
