摘要：径向浮动式齿轮泵是一种外啮合齿轮泵的新结构。在外啮合的齿轮泵上插装一个如附图所示的径向密封块１１，依靠油压，径向密封块紧压在侧板６和齿轮副１、５的外圆上，依靠侧板的限位作用，径向密封块１１和轴套４产生微量挠性变形补偿装置，至使泵获得最佳的径向密封。轴套式齿轮泵也可采用类似的补偿装置。Ｐ区为高压区，高压区的缩小，减少了径向力，因此本发明的齿轮泵性能提高了，可以实现齿轮泵的高压力、高效率和长寿命。如果从出口Ｂ加入高压油，在泵的输出轴上可以获得扭矩，齿轮泵可以变成齿轮马达。按中心对称安装二个径向密封块，即成为能正、反旋转的齿轮马达。

摘要： PURPOSE:To permit to feed ready mixed concrete the like by pressure into a transporting tube simply and smoothly by a method wherein an eccentric rotor is rotated along the inner peripheral surface of a casing and the substance to be sent is introduced and sent by pressure by providing a biting preventing rotor at the entrance of the casing. CONSTITUTION:The eccentric rotor 7, whose eccentric part 5a is rotated under contacting with the inner peripheral surface of the casing 1 in the condition of surface contact, is provided in the casing 1. The biting preventing rotor 11, which rotates intermittently, is provided at the entrance port 2 of the casing. A semi-tubular half-rotating valve 6, provided at the intermediate part of the entrance port 2 and a delivery port 3, is controlled by an operation control means so as to swing within a given angle under contacting with the inner peripheral surface of a cover 7. A force is applied to the valve 6 into the same direction as the rotating direction of the eccentric rotor 5 by a lever, cooperating through a shaft 8, and a weight at the end of the lever. According to this method, a process, from the introduction of the substance to be fed, such as the ready mixed concrete or the like, to the sending by pressure, may be separated at the intermediate part of the entrance port 2 and the delivery port 3, therefore, the substance may be sent by pressure smoothly into circumferential one direction.

摘要： PURPOSE:To increase pumping pressure, by constructing a pump by combining a plurality of rotors of twisted cubes with an oval cross-section and rotating them at the same speed. CONSTITUTION:A pump chamber comprises a plurality of rotors of twisted cubes 2 with an oval cross-section. A central hollow portion 3 is formed by the cubes 2. The cube 2 are such that they are brought into contact with a side surface of an adjacent cube at all times and they are rotated at the same speed. Thus, a volume of the central hollow portion changes for effecting pumping action. As a result, a construction is simplified and pumping pressure can be increased.

摘要： The rotary compressor consists of two cylinders of different size lying eccentrically one inside the other. The outer (2) and inner (3) cylinders are connected by a defined number of vanes (4) which are mounted to pivot on the inner wall of the outer cylinder. The shape and size of the vanes, and the size of the inner and outer cylinders and their relative position, determines the compression ratios. The outer cylinder is driven by a drive shaft (6) and thereby set in rotational movement, changing the working chamber (5) between the vanes.

摘要： The invention relates to a screw pump comprising an inlet cross-section and an outlet cross-section for conveying free-flowing media, in particular plastic melts and rubber blends. Said pump comprises two screw shafts (20, 21), having a distance (alpha) between their axes, which are located in a pump housing (3) comprising two partially overlapping housing bores (4, 5) that run through said housing (3) in a longitudinal direction and which can be rotationally driven in an equidirectional manner. A plurality of single-flight screw element groups (1, 2), which closely intermesh, are arranged on said shafts in a rotationally-fixed manner. The invention also relates to a multi-screw extruder comprising a screw pump of this type.
