ジング／の内側と連通ずる。As shown in FIG. 7, a portion of the housing l of the internal combustion engine is used as the pump housing l' which accommodates all the components of the pump. In the housing l', a radial thrust bearing 3' supports a secondary liquid feeding gear 3 having internal teeth, and the primary liquid feeding gear located inside this supports the secondary liquid feeding gear 3 with respect to the rotational axis of the secondary liquid feeding gear 3. It is eccentrically arranged and engages the secondary liquid delivery gear.・The primary liquid feeding gear is a freewheel type and is placed on a hollow shaft. This hollow shaft is arranged eccentrically with respect to the axis of rotation of the secondary pumping gear 3 and is firmly placed in the opening S of the housing l' of the pump. In the axial direction, the secondary pumping gear is supported on the side by a thrust bearing surface formed in the pump housing l', which is fastened to the pump housing l' by a suitable bolt. Lean on the other side of the lid/θ□. The lid lO is provided with a circular aperture // in the area of the hollow shaft through which the hub of the primary liquid delivery gear projects. Its extension forms the driven part 1.2' of the articulating joint 12 belonging to the centrifugal regulator /3 arranged on the other side of the lid 10, which driven part 72' engages the drive part 12'' of the articulating joint saw. The centrifugal regulator /3 is rotatably rounded into a hollow @+4!, and on the outer surface of i/0 near the 1INlltj circular aperture // of the regulator hub formed as an annular sealing surface 15. The gear wheel /3' on the circumference of the centrifugal regulator 13 engages with the drive wheel /da, which is firmly distributed on the camshaft of the internal combustion engine.The housing l of the pump
Inside the hollow shaft, there is a pressure passage 6 that extends from the opening S in which the hollow shaft is disposed to the circumference of the pair of liquid feeding gears, and this passage 6 communicates with the pressure duct S' of the hollow shaft. Radially opposite 1111 from the channel A is a suction channel 7 with a filter g extending from the periphery of the same liquid feed gear 2.3 to an opening 9 provided in the lid, thereby draining the internal cavity of the pump housing /'. communicates with the inside of the internal combustion engine housing.

This is achieved by an interlocking joint saw between the centrifugal regulator 13 and the drive gear /3', which engages the drive gear /3' distributed on the camshaft of the internal combustion engine. The primary liquid feeding gear h' arranged eccentrically with respect to the secondary liquid feeding gear 3 forms an intermediate liquid feeding space between the inner periphery of the secondary liquid feeding gear 3 and the outer periphery of the primary liquid feeding gear 3. .

１仰は蓋ｉｏの外面に接する。When the primary liquid feeding gear rotates clockwise, this intermediate liquid feeding space increases to the halfway point of the circumferential path between the suction passage 7 and the pressure passage 6, and then the button intermediate liquid feeding space increases. The liquid begins to decrease half way down the gear and the oil begins to be pumped into the pressure passage A (Figure 2). From here the pressurized oil flows into the pressure duct s' in the hollow shaft. The oil is introduced from the internal combustion engine's oil stop into the pump housing through a rectangular opening 9.
This is achieved through a filter g' arranged in the chamber and from there into the suction channel 7. A sufficient pressure difference between the suction area and the pressure area of the pump and its surroundings is ensured by properly selecting the gap between the two pumping gears, their own curvature, and the gap between the pumping gears and the housing. This is achieved by - Lid approximately equal to the hub of the next liquid feeding gear
The aperture ii at θ is sealed by the annular sealing surface 15, as described above, so that one side of the hub belonging to the centrifugal regulator rests on the outer surface of the lid io.

れる。The oil pump can operate both when the prime mover shaft is in the horizontal position and in the vertical force position. When the motor shaft is in the vertical position, the oil pump 1 is submerged in oil, so that only a pressure effect is required for its starting. When the prime mover shaft is in the horizontal position, the oil pump measures the oil level in the internal combustion engine housing. Located above. In such a position, the oil pump V'i must have a suction effect, which is obtained by locating the suction channel above the pressure channel.
この方式で油は常にポンプの中に残シ、これによって吸
引効果が得られる。In this way, oil always remains in the pump, which creates a suction effect.
