摘要： The invention relates to a sealing system for sealing a cylinder head (2) against a cylinder sleeve (1) of a single- or multi-cylinder internal combustion engine, notably a four-stroke diesel engine, with a divided cast iron crankcase consisting of two half-shells (3) connected to each other by screws, and wherein the joint plane runs in the direction of the crankshaft and the cylinder axis. The half-shells (3) comprise recesses for housing separate cylinder sleeves (1) and separate cylinder heads (2) are provided for each cylinder. The inventive sealing system comprises an annular sealing element. An annular groove (7), being open towards the combustion chamber, is provided in the cylinder head (2) and arranged in such a way that at least part of the prolongation of the cylinder sleeve (1) configured as sealing unit (5) is housed thereby forming a press fit. The annular sealing element is configured as a separate annular seal (4) which is supported on a sealing surface of the cylinder head (2) and radially supported on a sealing surface of the half-shells (3). Said annular seal thereby seals an annular gap (16) between the radially outer peripheral surface of the cylinder head (2) and the recesses of the half-shells.

摘要： The invention relates to a pressure valve in the form of a nozzle valve with constant volume relief to be fitted in the pressure line of a self-ignited internal combustion engine, said valve comprising a valve holder, a valve cylinder, and a valve body. The valve is characterized in that the valve body has at least one first spill port that branches off from the fuel channel, and in that the valve cylinder has a second spill port associated with the spill port of the valve body. Said spill ports, in the closed position of the pressure valve, communicate with each other or can be linked during the transition into the open position and form a link between the fuel channel and a suction chamber of the pump element.

摘要： The invention relates to a power generating installation that comprises a generator and a reciprocating internal combustion engine as drive, especially a synchronous generator and a diesel engine. Permanent magnets are disposed in the rotor of the generator in the pole zone to induce the rotor and a rotor winding (28) in the stator. In the pole zones of the rotor (29) at least one receiving pocket (34) is disposed in the axial direction and is open at least on one side. Said receiving pocket, with a cylindrical peripheral wall (50), borders the air gap (33) formed with the stator (11). The permanent magnets of the pole zone are constituted by a plurality of magnet elements (35) that are located side by side in the peripheral direction within the receiving pockets (34).

摘要： The invention relates to a method and system for assembling an electricity generating unit consisting of a generator and a reciprocating engine as the drive, in particular for centring an internal stator that is positioned inside an external rotor with an air gap. Said method comprises the following steps: mounting the external rotor onto the drive motor and connecting the rotor to the drive system of said motor; inserting at least two centring bolts, which are offset in the peripheral direction, into centring grooves that are provided in the rotor/stator for partially receiving, (when viewed from a radial direction), said centring bolts that bridge the air gap; centring the stator in the rotor by inserting said stator along the centring bolts inside the rotor; fixing the stator to the generator housing and fixing said generator housing to a connection housing of the drive motor; removing the centring bolts from the air gap.

摘要： The invention relates to an air-cooled internal combustion engine with a crankshaft which rotates about a vertical axis, especially a single cylinder diesel motor. Said internal combustion engine has an encapsulation which surrounds the cooling air channels. The flywheel is positioned at the top end of the crankshaft (1), said flywheel being combined with a radial blower (3). An air distribution housing (4) which is joined to the top front wall (2) of the crankcase forms the pressure chamber (5) of the radial blower (3). At least two sub-streams of cooling air branch off from said pressure chamber (5), a first sub-stream (L1) being guided through a housing encapsulation (21) which surrounds the cylinder (10) and the cylinder head (11) and a second sub-stream (L2) being guided in a lining (22) on the outside of the side wall (12) of the crankcase and the oil pan (13) facing the cylinder. Both sub-streams of cooling air (L1, L2) are collected on the downstream side and exit through a common air-extractor shaft.

摘要： A fuel injection pump for internal combustion engines, in particular one-cylinder diesel engines, has a pump piston (1) which can axially slide and rotate in a pump cylinder (13) with at least one fuel suction bore (14), a driving groove (6) arranged on the pump piston (1) and which is connected to a stop groove (5) for stopping fuel supply which extends on the pump piston (1) parallel to the piston longitudinal axis, and a geometrical connection between the front side (4) and the outer surface of the pump piston (1). In order to hydrodynamically regulate the optimum injection beginning during start, idle running and highest speed of rotation, a narrow slot (2, 7) is provided as geometrical connection.
