摘要： An oil pump apparatus, including a pump mechanism portion for discharging operating fluid, a valve-receiving bore formed in a housing, a flow control valve arranged in the valve-receiving bore connected to a bypass hole, and a bypass passage. The bypass passage is connected to the bypass hole, having a space radially extending from an edge of the bypass hole in a fluid stream direction of the excess operating fluid spouting from an opening area of the bypass hole. When fluid stream of the excess operating fluid reaches the inner surface of the bypass passage, the pressure of the excess operating fluid has been weaken sufficiently because fluid stream of the excess operating fluid is diffused by the long span of the bypass passage extended from the edged of the bypass hole. Therefore, the inner surface of the bypass passage is protected from cavitation damages and erosion.

摘要： A hydraulic fluid discharged from a pump is delivered to a power steering device from a supply passage through a restricted passage and a throttled passage so that as the flow through the supply passage increases in response to an increase in the number of revolutions of the pump, the flow path resistance presented by the restricted passage increases the pressure prevailing in the supply passage to cause a control spool to control the flow area of the throttled passage, thus decreasing the flow delivered to the power steering device. In this manner, a constant and invariable flow decrease characteristic can be maintained despite a loading pressure upon the power steering device, thus enhancing the stability under high speed running conditions. A mechanism to provide a variable control of the flow delivered to the power steering device is provided in a union which is fixedly mounted in one end of a bore in a pump housing.
摘要翻译： 从泵排出的液压流体通过限制通道和节流通道从供应通道输送到动力转向装置，使得当响应于泵的转数的增加而流过供给通道的流量增加时， 由限制通道提供的流动阻力增加了供给通道中的压力，使得控制阀芯控制节流通道的流动面积，从而减少了传递到动力转向装置的流量。 以这种方式，即使在动力转向装置上施加负载压力，也可以保持恒定且不变的流动减小特性，从而提高高速运行条件下的稳定性。 提供到输送到动力转向装置的流量的可变控制的机构设置在固定地安装在泵壳体中的孔的一端中的联接件中。

摘要： A transmission ratio variable mechanism in prior art provided on a steering column needs a spiral cable and hence, not only needs an extra space but is also accompanied by a risk of having a drawback such as the breakage of the cable or the like. A steering wheel shaft 11 and an output shaft 22 are supported in a housing 21 attached to a steering column 13, to be rotatable on the same axis; first and second sun gears 45, 46 different slightly in the number of gear teeth are formed on facing end portions of the steering wheel shaft and the output shaft; first and second planetary gears 53, 54 meshing with the first and second sun gears are supported on a carrier 47; and a worm shaft 58 meshing with a worm wheel 57 connected rotationally to the carrier is constructed to be rotatable by a motor 43 which is provided on the housing in a direction perpendicular to the rotational axis of the steering wheel shaft and the output shaft. Thus, it can be realized to eliminate any spiral cable and to obtain a transmission ratio variable steering device 10 which is space-saving.

摘要： In a pump housing of a pump apparatus, a pump shaft is rotatably supported by two bearings and is connected to a pump unit. A rotary drive member is fixed to one end of the pump shaft projecting from the tip end portion of the housing. The rotary drive member includes a boss portion fixed to the one end of the pump shaft projecting from the housing, and a rim portion integral with the boss portion. The rim portion is offset from the boss portion to cover at least a portion of the tip end portion of the housing. A groove portion for receiving a drive belt is formed on the outer circumference of the rim portion. The widthwise center plane of the groove portion is located between the respective centers of the two bearings. In place of the groove portion, a tooth portion engageable with a drive gear may be formed on the outer circumference of the rim portion. Preferably, the pump unit is of a balanced vane type.
