    • The distance A between opposite end nozzles 4e and 4e on the nozzle plate 4 is set smaller than the distance B between opposite end link channels 3e and 3e in the actuator. The difference between the distances A and B is determined dependent on the difference between the thermal expansion coefficients of the actuator and of the nozzle plate. After being heated, the nozzles will be properly located in correspondence with the ink channels. During the heating step, the nozzle plate is placed on the actuator via an adhesive. Then, the heater block is placed on the nozzle plate to heat the adhesive via the nozzle plate and to press the nozzle plate from upwardly. Accordingly, the temperature of the adhesive rapidly increases, whereby gas is completely discharged from the adhesive before the adhesive is completely hardened.
    • 喷嘴板4上的相对端部喷嘴4e与4e之间的距离A被设定为小于致动器中相对端连杆通道3e和3e之间的距离B。 距离A和距离B之间的差别取决于致动器和喷嘴板的热膨胀系数之间的差异。 在加热之后,喷嘴将适当地位于与墨水通道对应的位置。 在加热步骤期间,喷嘴板通过粘合剂放置在致动器上。 然后,将加热器块放置在喷嘴板上,以经由喷嘴板加热粘合剂,并从上方按压喷嘴板。 因此,粘合剂的温度快速增加,在粘合剂完全硬化之前,气体从粘合剂中完全排出。

    • A radial piston pump for low-viscosity fuel according to a first aspect of the invention comprises a pump housing, which is constituted of as few as two structural bodies (from among a drive-side housing member 2A, a fixed cylinder 81 and a cover 4), and a leaf valve member 82 which is formed with intake valves 87 for opening and closing intake side passages 27 and discharge valves 88 for opening and closing discharge side passages 28 and is sandwiched between two structural bodies (fixed cylinder 81 and cover 4). The first aspect of the invention reduces the number of components constituting the pump housing, enables highly precise overall axial alignment, prevents wobbling of a pump shaft 9 of the pump, increases performance and reliability and reduces cost. A radial piston pump for low-viscosity fuel according to a second aspect of the invention comprises a leaf valve member 205 formed in one and the same plane thereof with overflow ports communicating with an overflow passage 59 in the pump housing, intake valves 87 communicating with intake side passages 27 and discharge valves 88 communicating with discharge side passages 28. The third aspect of the invention provides a method for assembling the radial piston pump for low-viscosity fuel according to the second aspect of the invention.
    • 根据本发明的第一方面的用于低粘度燃料的径向柱塞泵包括泵壳体,其由少至两个结构体(从驱动侧壳体构件2A,固定气缸81和盖子 形成有用于打开和关闭进气侧通道27的进气门87和用于打开和关闭排出侧通道28的排出阀88并且被夹在两个结构体(固定缸81和盖4)之间的叶片阀构件82 )。 本发明的第一方面减少了构成泵壳体的部件的数量,使得能够进行高精度的总体轴向对准,防止泵的泵轴9摆动,提高了性能和可靠性并降低了成本。 根据本发明第二方面的用于低粘度燃料的径向柱塞泵包括在其一个同一平面中形成有与泵壳体中的溢流通道59连通的溢流口的叶片阀件205,进气门87与 进气侧通道27和与排出侧通道28连通的排出阀88.本发明的第三方面提供一种组装根据本发明第二方面的用于低粘度燃料的径向活塞泵的方法。
