摘要： At the time for forming an internal gear from a raw material 2 of an internal gear, first, the raw material 2 is externally inserted onto a forming die 3 and fixed to the forming die 3 through a pressing die 4. Next, a forming roll 5 is moved in a direction as indicated by an arrow B of FIG. 6 while rotating the forming die 3. By this, the inner peripheral surface of the raw material 3 is pressed against an outer gear part 3b formed on the outer peripheral surface of the forming die 3 so that an internal gear part 1c is formed on the inner peripheral surface of the raw material 2. The rotating direction of the forming die 3 is selected such that the first end part of the outer gear part 3b located on the front side in the feeding direction of the forming roll 5 is moved ahead in the rotating direction (the direction as indicated by an arrow A of FIG. 6) of the second end part located on the rear side in the feeding direction of the forming roll 5.

摘要： The plunger pump according to the present invention discharges fuel by reciprocation of a plunger, and comprises metallic diaphragm type dampers, provided at a fuel inlet side and a fuel outlet side, respectively, for reducing pressure pulsation of fuel. Each metallic diaphragm type damper comprises a pressure chamber for receiving fuel pressure, a back pressure chamber into which gas is charged, and a metallic diaphragm for defining the pressure chamber and the back pressure chamber. Since the metallic diaphragm type dampers are provided at the fuel inlet side and the fuel outlet side, respectively, noise and vibration caused by pressure pulsation are reduced at the fuel inlet side and the fuel outlet side. Also, since the diaphragms are metallic diaphragms, deterioration thereof generated by fuel liquid and back pressure gas is low, reliability is high, and the lifetime is long.
摘要翻译：根据本发明的柱塞泵通过柱塞的往复运动来排出燃料，并且分别包括设置在燃料入口侧和燃料出口侧的金属隔膜式阻尼器，用于减少燃料的压力脉动。每个金属隔膜式阻尼器包括用于接收燃料压力的压力室，用于充气的背压室和用于限定压力室和背压室的金属隔膜。由于金属隔膜式阻尼器分别设置在燃料入口侧和燃料出口侧，所以在燃料入口侧和燃料出口侧分别导致由压力脉动引起的噪声和振动。此外，由于隔膜是金属隔膜，因此燃料液和背压气体产生的劣化低，可靠性高，寿命长。

摘要： A diaphragm type damper has a combined member, which is formed by welding a marginal portion of a diaphragm to a half body having a concave portion formed therein, and is fixed to a pressure chamber portion to which high pressure fluid is introduced. A wall thickness of a welding portion of the half body is not relevant to welding, and the heat capacity of the welding portion is small. Since the half body is allowed to have a large wall thickness, leakage from the welding portion and damage to that portion can be prevented. In addition, the diaphragm type damper of this present invention can be easily assembled, since it requires only fixing the combined member to the pressure chamber portion.
摘要翻译：隔膜式阻尼器具有组合构件，该组合构件通过将隔膜的边缘部分焊接到其中形成有凹部的半体形成，并且被固定到高压流体被引入的压力室部分。半体焊接部的壁厚与焊接无关，焊接部的热容小。由于允许半体具有较大的壁厚，因此可以防止焊接部分的泄漏和对该部分的损坏。此外，本发明的隔膜式阻尼器可以容易地组装，因为它仅需要将组合的构件固定到压力室部分。

摘要： A receiving portion 2e for rotatably receiving therein a planetary gear 3, is formed between a plurality of retaining protrusions 2d of a carrier. A connection portion 2f extending annularly about a rotation axis L is formed on an outer peripheral of a distal end portion of each retaining protrusion 2d. Through this connection portion 2f, the distal end portions of the respective retaining protrusions 2d are connected to each other. Owing to this arrangement, each retaining protrusion 2d is reinforced to minimize its deformation. As a result, deformation of the receiving portion 2e is greatly reduced and the planetary gear 3 receiving in the receiving portion 2e can rotate smoothly.
