    摘要： The invention relates to a pump which assures high reliability while maintaining the functionality as a compact, inexpensive motor-mounted internal gear pump. The pump includes an inner rotor with teeth on its outer surface, an outer rotor with teeth on its inner surface to engage with the inner rotor teeth, a pump casing housing both the rotors, and an inner rotor support shaft which pivotally supports the inner rotor. The motor includes a rotator located inside the pump casing, and a stator located outside the pump casing. The pump casing includes two casing members which face both side faces of the outer rotor and the inner rotor and have an outer rotor bearing which pivotally supports both sides of the outer rotor. The inner rotor support shaft has an inner rotor bearing eccentric to the outer rotor to support the inner rotor pivotally in a rotatable manner and connects the two casing members virtually concentrically with the outer rotor bearing.

    摘要： As pressure in a water tank rapidly rises when water inside a compressor is evaporated by the high temperature of compressed air and this situation makes the operation unstable, an object of the present subject matter is to address this problem. A water injected scroll air compressor is provided with: an air end of the scroll air compressor; a driving unit that generates driving force for the air end; a compressing path from a suction port to a discharge port; a portion to inject water into the compressing path; a discharge piping of air discharged from the air end; a tank provided on a path of the discharge piping for storing water separated from the compressed air; and a cooler that is provided on the path of the discharge piping between the tank and the air end and cools the compressed air discharged from the air end.

    摘要： An oil separator and an oil reservoir are formed integral with a main casing. Also, an opening communicated with the oil reservoir is formed in a part of a lower portion of an oil separation space of the oil separator. Preferably, the opening is formed so that its width is increased as it approaches an outer peripheral side of the oil separation space from a center thereof. Further, a safety valve is installed so that a line connecting between the safety valve and the center of the oil separator is made substantially in parallel to axes of screw rotors.

    摘要： A screw rotor for use in screw compressors and screw vacuum pumps comprises a pair of rotors including a male rotor and a female rotor. These rotors have helical lobes in an axial direction and mesh with each other to form a compression chamber. Depending upon a lobe configuration of the rotors, suction pressure and discharge pressure, a negative torque for self-rotation as well as a positive torque opposing to rotation due to a compression action is generated on the female rotor in operation. This phenomenon generates when a value obtained by integrating a torque acting on the female rotor over an entire cross section in an axial direction of the rotors becomes negative. When the negative torque is generated, noises due to tooth separating vibration is caused. Then, a lobe profile is defined such that a magnitude of the negative torque is smaller than that of the positive torque in respective cross sections of the female rotor. That is, a relationship between a radius of a point of contact on a leading surface side of the female rotor and a radius of a point of contact on a trailing surface side or curvatures of the rotors are such that the negative torque is not generated on the lobe profile.

    摘要翻译： 用于螺杆式压缩机和螺杆式真空泵的螺杆转子包括一对转子，包括一个公转子和一个母转子。 这些转子在轴向上具有螺旋形叶片并且彼此啮合以形成压缩室。 根据转子的凸角构造，吸入压力和排出压力，在操作中在母转子上产生自旋转的负转矩以及由于压缩动作而与旋转相反的正转矩。 当通过将在母转子上作用的转矩在转子的轴向上的整个横截面上积分得到的值变为负时，会产生这种现象。 当产生负转矩时，会引起由于齿分离振动引起的噪音。 然后，定义凸角轮廓，使得负转矩的大小小于阴转子的相应横截面中的正转矩的大小。 也就是说，阴转子的前表面侧的接触点的半径与后表面侧的接触点的半径或转子的曲率之间的关系使得不产生负转矩 肺叶剖面。
