TH67594A - Rotary oil pump on shaft - Google Patents

Abstract

DC60 (03/09/47) The purpose of this invention was to equip a rotary oil pump on the shaft. The wear and tear of the rotating surface is caused by air bubbles in the liquid under pressure. That low is reduced to a minimum The vibration and noise are reduced, and the structure has been greatly simplified. Rotary oil pump on the shaft of the This fabrication consists of a revolving chamber with inlet and outlet, outer and inner swivel parts. And a shallow groove which forms on the side of the initial tip of The outlet on the circular circumference of the incision line of the buttocks of the tooth, where From the rotation of the outer pivot part In the state of closed gaps caused by the Spin around outside Internal pivot section and partition between the end of the channel. Inlet and initial end of the ejection channel Will have a reduced volume from the maximum volume The closed gap Sa is then transferred to the shallow groove. The purpose of this invention is to provide a rotary oil pump on the shaft, where the wear of the rotating surface. This is caused by air bubbles in the liquid under low pressure are minimized. Reduced vibration and noise And the structure has been greatly simplified. The rotary oil pump on the shaft of this invention consists of a rotary chamber with inlet and outlet, outer and inner swivel parts. And shallow groove formed on the side of the initial end of the discharge channel, on the circumference of the incision of the buttocks of the tooth, formed by the rotation of the periphery. In the condition that the closed gaps caused by the external rotation part Internal swivel and divider between the end of the inlet and the starting end of the discharge port. The volume will be reduced from the maximum volume. The closed gap Sa will be transferred to the shallow groove.

Claims (5)

1.Rotary oil pump on a shaft consisting of: a rotary chamber with inlet and outlet vent. The outlet and the inner rotor and the risers made on the first end of the vent, on the circular circumference of the path of the tooth bottom position formed by the rotation of the outer rotor, where In the condition where the sealed space is formed by the outer rotor, it The dial in the said winder and the barrier between the end of the said intake inlet and the first end of the outlet, as such, is reduced from the maximum value. The starting position is separated by a long distance away from the bottom of the rotator inside it. The risers do the same or do not use the same on the circular circumference of the path of the bottom position of the spinner teeth. The sealed empty space, moving to the first end of the outlet, is connected to the risers. The sealed space becomes a volume area. And areas with such volumes are contacted with shallow grooves and are drained through the said vents. 2. The rotary oil pump on the shaft according to claim 1, where the vacancy is sealed, is the largest. The free space is contacted with the shallow furrow in a condition where its volume is reduced by 1% to 6%. 3. A rotary oil pump on an axle in accordance with claim 1 or 2, where the shallow groove is greatly rounded or linear in the longitudinal direction. And the distance from the circular circumference of the path to the outer scaffold of the risers and the circular circumference of the path to the inner scaffold is equal to the circumference of the path of the peripheral tooth position. 4. A rotary oil pump on an axle in accordance with claim 1 or 2, where the shallow groove is greatly rounded or linear in its longitudinal direction. And the distance from the circumference of the path to the outer scaffold of the risers and the circular circumference of the path to the inner scaffold differ on the circular circumference of the path of the bottom position of the spinner teeth. 5. A rotary oil pump on a shaft consisting of Rotary storage chamber with suction inlet and outlet vent The outlet and the inner rotor and the risers made on the first end of the vent, on the circular circumference of the path of the bottom position of the lightning formed by the rotation of the outer rotor at Which in the condition where the area has volume By the said outer rotor The stopper and the barrier between the last end of the said inlet and the first end of the said vent is the greatest. The volumetric area is connected to the aforementioned risers located on the circular circumference C of the periphery path 6b, the outer rotor 6, which is separated by a long distance T from the bottom of the tooth 5b. Inlet 5 or the said inlet and the groove thereof
