Shaped article made of plastic

Prior art throttle-valve housings made of plastic have a tubular metal insert in order to ensure accuracy to size in the region of the regulating flap. This is costly and complex, however. The throttle-valve housing proposed is simple to manufacture and can be manufactured with a high accuracy to size in spite of being made of plastic. The plastic housing (1) encloses a hollow space (2) delimited by the inside surface (3) of the housing wall. Embedded in the wall (15) is an insert (6) which is completely surrounded by plastic and which stabilizes the plastic, thus preventing the plastic from distorting, shrinking, etc., and ensuring a dimensionally accurate inside wall surface (3). The throttle-valve housing proposed is particularly suitable for use in the engines of motor vehicles.

External rotor pump

The invention relates to an external rotor pump, in particular a hydraulic external rotor pump, having a first component which is configured as an outer rotor with a sliding surface which is arranged on the outer side thereof, and having a second component which is configured as an opposing body and in which the outer rotor is mounted rotatably by means of the sliding surface thereof on an inner guide surface of the opposing body and is in mechanical contact with said inner guide surface. Furthermore, an inner rotor which is mounted such that it can be rotated eccentrically with respect to the outer rotor is provided. One of the rotors can be driven, in order to be set into a rotational movement, and the rotors are coupled to one another in such a way that, when the drivable rotor is driven, the other rotor is likewise set into a rotational movement as a result, in order to convey fluid from a suction region to a pressure region of the external rotor pump. The sliding surface or the guide surface has a surface structure which has a load-bearing region and a non-load-bearing region which is depressed in contrast with the former, with the result that the non-load-bearing region is saved from the contact between the guide surface and the sliding surface which is mounted thereon. In addition, the invention relates to various uses of an external rotor pump of this type, in particular as a conveying means for conveying lubricant, fuel or combustibles or liquids with a high viscosity at a high pressure or high temperature.

本发明涉及一种外转子泵、尤其是液压外转子泵，包括构造为外转子的第一构件，其在外侧上设有滑动面，以及包括构造为配合体的第二构件，在其中外转子借助其滑动面可转动地支承在配合体的内导向面上并且与之机械接触。此外，设置有偏心于外转子可转动地支承的内转子。所述转子之一可驱动，以便进行旋转运动，并且所述转子这样相互耦合，使得当可驱动的转子被驱动时，另一转子由此也进行旋转运动，以便将流体从外转子泵的吸入区域输送到压力区域。所述滑动面或导向面具有表面结构，该表面结构具有支承区域和相对于该支承区域凹陷的非支承区域，使得非支承区域免于在导向面和支承其上的滑动面之间的接触。本发明还涉及这种外转子泵的不同应用，尤其是用作用于在高压或高温下输送具有高粘度的润滑剂、燃油或燃料或液体的输送装置。

External rotor pump with a surface structure having a load-bearing region and a non-load bearing region

An external rotor pump has an outer rotor with a sliding surface which is arranged on the outer side thereof, and an opposing body in which the outer rotor is mounted rotatably by way of the sliding surface thereof on an inner guide surface of the opposing body and is in mechanical contact with the inner guide surface. An inner rotor which is mounted such that it can be rotated eccentrically with respect to the outer rotor is provided. The sliding surface or the inner guide surface has a surface structure which has a load-bearing region and a non-load-bearing region which is depressed in contrast with the former.

Power generating device

在涡旋压缩机中，在公转涡旋部件1的公转涡卷支承圆板1b的一面上直立设置公转涡旋涡卷1a，在另一面上连接公转圆板2，在公转圆板2的中心部形成插入偏心轴4a的公转轴支孔2b，在公转轴支孔2b的外周部形成插入制约公转涡旋部件1的自转的偏心轴5e的曲柄轴支孔2a，由合成树脂使公转涡旋涡卷1a和公转涡卷支承圆板1b整体成型，使公转圆板2为金属纱材料，将公转轴支孔2b和曲柄轴支孔2a整体成型，由此，抑制公转涡旋部件1的热变形，防止涡卷接触引起的磨耗或机械损失等。

Piston for radial pump for motor vehicle brake system

The piston comprises a hollow body (1) which carries a non-return valve (12). The body is made from easily worked material and is reinforced at the end (10) against which the drive eccentric operates, e.g. free machining steel reinforced with a hardened steel ball (18) or a plastic such as PEEK locally reinforced with glass fibre. The injection-moulded plastic valve has an elliptical cross section (16) in the region of the seating surface (4), and has two or more integral hooked retaining fingers (13) which engage with an internal lip (14) in the bore of the body to hold the valve captive.

Compressor

The purpose of the present invention is to mitigate or prevent a decrease in the mass flow rate of a fluid being discharged. A compressor 100 is provided with the following: a housing 10 that extends in one direction; an internal housing 40 that is disposed between an intake chamber H1 formed on one end in the housing 10, and a discharge chamber H2 formed on the other end in the housing 10; and a movable scroll 3 that is a compression mechanism that is provided in the internal housing 40, that compresses a fluid guided into the intake chamber H1, and that discharges the compressed fluid into the discharge chamber H2. The housing 10 includes a front housing 11 having an internal wall surface W1 that is exposed to the intake chamber H1, a rear housing 13 having an internal wall surface W2 that is exposed to the discharge chamber H2, and a center housing 12 that connects the front housing 11 to the rear housing 13 and has a thermal conductivity lower than the thermal conductivity of the rear housing 13.
