    • An oil injection type screw compressor includes an oil passage for circulating lubricating oil extending from an oil separator disposed in a discharge passage of a compressor main body through an oil cooler, oil filter and oil pump on the downstream side of the oil pump to parts requiring lubricating oil such as rotors, bearings, shaft sealing members within the compressor main body, the compressor comprising pressure switches for detecting a pressure of a suction passage as a low pressure side, and a pressure of the oil passage between the oil filter and the oil pump as a high pressure side, whereby starting the oil pump when the differential pressure between both the detected pressures is not more than the specified value.
    • 一种注油式螺杆式压缩机,其特征在于,具备将从设置在压缩机主体的排出通路中的油分离器延伸的润滑油通过油泵的下游侧的油冷却器,油过滤器,油泵, 润滑油,例如转子,轴承,压缩机主体内的轴密封构件,压缩机包括用于检测作为低压侧的吸入通道的压力的压力开关以及油过滤器和油之间的油通道的压力 泵作为高压侧,由此当两个检测压力之间的压差不大于规定值时启动油泵。

    • A motion guide device has a moving block mounting surface 501 of an end plate 5 formed in a planar shape and a thinned-down portion 52 formed in an opposing moving block mounting surface 502. Moreover, in this motion guide device, a lubrication path 30 includes: a first lubrication path 30a formed extending in a horizontal direction from a surface of side surfaces parallel to a longer direction of a track rail 1 in the end plate 5 to a central portion of the end plate 5; a second lubrication path 30b formed in the central portion of the end plate 5; and a third lubrication path 30c connected to the second lubrication path and formed in a groove shape in the moving block mounting surface 501 of the end plate 5, and, moreover, the first lubrication path 30a is formed in a hollow shape continuous to inside a built-up portion 52a appended to the thinned-down portion 52 of the end plate 5. Having such a configuration enables this motion guide device to achieve an average dispersal of lubricant to each of rolling element circulation paths regardless of mounting position of a greasing nipple with respect to the end plate, type of lubricant, and so on.
    • 运动引导装置具有形成为平面形状的端板5的移动块安装面501和形成在相对移动块安装面502中的减薄部52.另外,在该运动引导装置中,具有润滑路径30 包括:从端板5中的平行于轨道轨道1的较长方向的侧面的水平方向形成的端部板5的中央部形成的第一润滑路径30a; 形成在端板5的中心部分的第二润滑通路30b; 以及连接到第二润滑路径并在端板5的移动块安装表面501中形成为凹槽形状的第三润滑路径30c,此外,第一润滑路径30a形成为连续到内侧的中空形状 构成部分52a附加到端板5的减薄部分52上。具有这种构造使得该运动引导装置能够实现润滑剂到滚动体循环路径中的平均分散,而与润滑乳头的安装位置无关 相对于端板,润滑剂的类型等。
