摘要： PROBLEM TO BE SOLVED: To prevent a decrease in pump efficiency and an increase in noise due to air intake without leading to an increase in manufacturing cost or size.
SOLUTION: A plurality of intake ports 31 are formed corresponding to expansion side spaces 22g through 22i, 22k in a group of spaces formed in a pump chamber 10. According to a control valve 7, the operation state of an oil pump 1 switches to a first state, wherein a plurality of intake ports 31 are communicated together via second and third ports 74, 73 of the control valve 7, and a second state, wherein hydraulic oil from a discharge port 33 of a supply passage 5 to either of a plurality of intake ports is fed through a first port 71 of the control valve 7 making the intake operation of a part of the expanded side spaces unnecessary. In addition, a communication hole 77c is provided which communicates a spring chamber 79a and a third port 73 with a second land 77a of the valve body of the control valve 7. Also, the shaft length of a first land 77b is made shorter than the shaft length of the opening portion of the third port 73.

摘要： PURPOSE: To improve work efficiency, to be favorable in reduction of size, and to improve mounting ability when an oil pump device is mounted on a car body. CONSTITUTION: When the number of revolutions of a rotor 2 is low and an oil pressure through a main delivery port 31 is low, the confluent port 74 of a control valve 7 is released. Oil in a first oil passage 61 through a main delivery port 31 and oil in a second oil passage 62 through a subdelivery port 32 are joined together at a confluent area 5T to ensure a necessary oil pressure. Meanwhile, when the number of revolutions of the rotor 2 and an oil pressure through the main delivery port 31 is increased, the valve body 77 of a control valve 7 is moved in a direction B2, the confluent port 74 is closed to block confluence. A second port 72 is communicated with a feedback port 73, and feedback of working oil in the second oil passage 62 through the feedback port 73 to a feedback oil passage 66 is carried out.

摘要： An oil pump system includes an oil pump, a first hydraulic passage, a second hydraulic passage, a return hydraulic passage, and a control valve. When a revolving speed of a rotor of the oil pump is low, and when a hydraulic pressure of a hydraulic oil, discharged out of a first outlet port of the oil pump to the first hydraulic passage, is lower than a predetermined value, a valve body of the control valve is placed at a first position, thereby joining the hydraulic oil, flowing in the first hydraulic passage, with the hydraulic oil, discharged out of a second outlet port of the oil pump to the second hydraulic passage, and delivering the thus joined hydraulic oil to a hydraulic oil receiving unit via a hydraulic-oil-delivery passage. When the revolving speed of the rotor is high, and when the hydraulic pressure of the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, is higher than the predetermined value, the valve body is placed at a second position, thereby inhibiting the hydraulic oil from joining, and delivering only the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, to the aforementioned destination. The oil pump system is downsized and lightweighted advantageously, and is improved in terms of work efficiency and on-boardability.

摘要： PCT No. PCT/SE79/00181 Sec. 371 Date May 2, 1980 Sec. 102(e) Date May 2, 1980 PCT Filed Sep. 6, 1979 PCT Pub. No. WO80/00591 PCT Pub. Date Apr. 3, 1980.A gear machine comprises two helical gears (1, 2) in mutual mesh for compressing or pumping a fluid. The suction side of the machine can be made conventionally. The outlet port (4) of the machine is made as a plurality of holes (14), extending in towards the meshing zone at one side of the gear pair. The plurality of holes opens at one end (14a) within a Y-shaped area comprising the union of the surfaces which are each defined by the respective gear top and bottom circles (K, L) between a plane (P) through the axes of the gears and a gear radius (R) forming an angle to the axis plane at most attaining B x (1/R) x tangent beta , where B is the width of the gear pair, R is the outside circle radius of the respective gear, and beta is the helix angle of the gears. At their other ends (14b), said holes are connected to a duct (6) at axially separated places in the duct, in the same order as they in the peripheral direction of the gears, open out onto said end surface. A sealing piston (7) is displaceably arranged in the duct, and one end (0) of the duct communicates with the fluid outlet of the machine so that the machine can be controlled at a constant rate of revolutions by displacing the piston in the duct.

摘要： 933,578. Gear pumps. G. SABATINI. Jan. 16, 1961 [Jan. 19, 1960], No. 1732/61. Class 110 (2). A pressure relief valve for a gear pump comprises a member 7 having arcuately-shaped recesses 7a engaging the gears 5 on the delivery side. The member 7 has a cylindrical extension 7b slidably mounted in the housing 8a, and is urged towards the gears by a spring 9. At a certain delivery pressure, the value of which may be varied by altering the compression of the spring by means of a threaded cap 10, the member 7 lifts from the gears 5, and the flow is reduced. The gears are immersed in the fluid and have only the member 7 disposed around their periphery. The spring 9 may be replaced by servo-control means. The member 7 may be pivotable instead of slidable.
