  • Blower for delivering cooling air to internal combustion engines
    Patent number: 4886418
    Abstract: A single stage axial blower design provides a series of blowers producing a wide range of delivery flow rates even though they have the same outer dimension, drive speed and guide wheel. This is achieved by a structural combination which includes a stationary guide vane wheel (5) of fixed design and impellers (8) which have varying hub diameters (9, 9a, 9b) but the same outer diameter. Thus, a series of blowers having the same external dimensions and the same stationary guide vane structure can be used with a series of air-cooled internal combustion engines which differ from one another in number of cylinders and related cooling requirements.

  • Internal combustion engine
    Patent number: 4834029
    Abstract: A cooling circuit (5) for an internal combustion engine in which a throttle (2) is provided upstream of a heat exchanger (10, 11). The throttle (2) equalizes the oil pressure in the internal combustion engine in front of the heat exchangers and insures that this occurs almost independently of the temperature of the oil. By this provision, the heat exchangers can be fabricated with the least expense since the danger of bursting is reduced.

  • Multiple piece piston for an internal combustion engine
    Patent number: 4831917
    Abstract: A multiple piece piston is provided for a diesel internal combustion engine having a combustion chamber depression in the crown of the piston. In order to achieve a low rate of heat flow into the piston ring area and thus into the cylinder liner which surrounds the piston, a separate piston base or crown surrounding the combustion chamber depression is formed by a ring element made of a material having poor thermal conductivity, and the main body of the piston is made of a material with high thermal conductivity. The heat of combustion is thus conducted mainly axially through the piston main body and absorbed by sprayed cooling oil. The cooling oil, thus heated, can be utilized for heating purposes.

  • Planter hydraulic system with means for locking row markers during transport
    Patent number: 4800962
    Abstract: A wide farm implement is provided with a swingable tongue which permits endwise to and from fields. A pair of transport wheels are provided for supporting the implement for endwise transport and the support wheels, on which the implement is supported during a field working operation, are raised so as not to interfere with endwise transport. In order to prevent the automatic lowering of a row marker when the support wheels are thus raised relative to the frame, a blocking valve is provided in the row marker hydraulic circuit which moves to its closed position when the tongue is moved from its field working position thereby preventing lowering of the row marker.

  • Internal combustion engine with fluid-cooled cylinder liner
    Patent number: 4794884
    Abstract: An internal combustion engine with a block cylinder head 7 and a fluid-cooled cylinder liner 1 has a cooling chamber between the cylinder liner 1 and the crankcase 2. The cooling chamber includes at least two partial cooling chambers 9a, 9b which are connected only by a connecting channel 8, and wherein the first partial cooling chamber 9a, which is adjacent to the cylinder head 7, is open in the direction of cylinder head 7 and passes over into a slot-shaped annular chamber 10 in cylinder head 7. A cooling arrangement for a cylinder liner for use with block cylinder heads is provided in which the cooling adjusts itself according to the quantities of heat which need to be removed, i.e., the thermal load is more uniformly carried over the entire axial length of the cylinder liners.

  • Fuel injection mechanism for an internal combustion engine
    Patent number: 4785787
    Abstract: A fuel injection system for a diesel engine in which an electromagnetically actuated valve determines the initiation and conclusion of injection. A valve of this sort consists of a primary slide valve component 3 which, in its closed position, makes a seating engagement with a tapered valve seat 5 to close a connecting channel 16 between the injection line 10 and a dumping passage 12. The primary valve component is moved to its open position by an electromagnetically actuated impact bolt 40. In order to avoid problems associated with seat valves, a second electrically operated valve component 6 is provided in a second connecting channel 25 between the high pressure channel 7 and the dumping channel 12.

  • Cylinder head
    Patent number: 4781158
    Abstract: An air-cooled block cylinder head adapted for mounting on an open-deck cylinder casing of an internal combustion engine. In order to maintain a tight seal of the cylinder head to the cylinder casing, the combustion chamber floor of the cylinder head is designed to be deflected in a manner that does not adversely affect the sealing of the cylinder head to the cylinder casing. This is achieved by designing the cooling chamber side of the cylinder head floor with a gradually changing floor wall thickness in the area directly above the cylinder combustion chamber. In the preferred designs, the combustion chamber floor is designed to be concave or convex. The cylinder head also includes features for effectively cooling the combustion chamber floor and for isolating the exhaust conduit.
