摘要： It is an object of the present invention to provide a trochoid type oil pump in which erosion of the rotor surfaces caused by cavitation is minimized, vibration and noise are reduced, and the structure is greatly simplified. The trochoid type oil pump of the present invention comprises a rotor chamber which has an intake port and a discharge port, an outer rotor, an inner rotor, and shallow grooves which are formed on the side of the initial end portion of the discharge port on the circular circumference of the track of the positions of the bottom portions of the teeth created by the rotation of the outer rotor. In a state in which the sealed spaces formed by the outer rotor, the inner rotor and a partition part between the final end portion of the intake port and the initial end portion of the discharge port are reduced in volume from the maximum volume, the sealed spaces Sa are caused to communicate with the shallow grooves.

摘要： The present invention provides an oil pump in which eroding of the inside of the pump due to cavitation and erosion is prevented by minimizing the pressure change in a fluid when inter-tooth spaces formed by an inner rotor and an outer rotor transport the fluid from the intake port to the discharge port. The oil pump comprises: an inner rotor; an outer rotor; an intake port; a discharge port; a transfer side partition part formed between a terminal end of the intake port and a leading end of the discharge port; and a shallow groove which is formed in the transfer side partition part, and which communicates with the discharge port but does not communicate with the intake port. The shallow groove does not intersect with the cell on the transfer side partition part, and is positioned farther inward than the circular locus of the gear bottom parts of the inner rotor. The shallow groove communicates with the cell through a side clearance between the transfer side partition part and the rotor side surfaces of the inner rotor and the outer rotor.

摘要： To provide a relief valve structure for an oil pump, which is capable of appropriately controlling/switching the discharge pressure and flow rate of oil to an optimum condition in low, middle and high speed regions of an engine. The relief valve structure has: a relief valve having formed therein a valve flow path for communicating between a valve head part and an outer circumferential side part; a valve housing in which a valve passage accommodating the relief valve is formed; a relief flow-in part formed on an axial direction one end side of the valve passage and communicating with the valve passage; a first discharge part formed in the valve housing and communicating with the valve flow path by the movement of the relief valve; and a second discharge part that is opened by allowing the valve head part to pass therethrough. The second discharge part is positioned nearer to the relief flow-in part than the first discharge part. The shortest gap between an outer circumferential side part opening of the valve flow path and the first discharge part is the same as or shorter than the shortest gap between the valve head part and the second discharge part during an initial state of the relief valve.

摘要： A power transmission apparatus is capable of easily passing lubricant toward a seal arranged between a higher shat and an opening of a case of the apparatus. The apparatus includes the higher shaft, i.e., a hollow connecting shaft that faces the outside of the transfer case through the opening of the transfer case. The oil seal is arranged between the hollow shaft and the opening of the transfer case. The hollow shaft meshes, through helical spur gears, with an intermediate transferring shaft that is positioned lower than the hollow shaft. A lubricant guide is arranged to receive lubricant splashed up by the ring gear and helical spur gear of the intermediate shaft and guide the received lubricant toward the oil seal and a ball bearin
