Abstract

기계를 고압화한 때에 펌프 스프링 자신에게 생기는 공진을 확실히 억제하도록 하고, 이에 의해 분사수의 맥동을 확실히 방지하는 것을 목적으로 한다.It is an object to reliably suppress the resonance occurring in the pump spring itself when the machine is pressurized, thereby reliably preventing pulsation of the sprayed water.

플런저(3)의 흡입 동작에 수반하여 스프링(5)을 힘을 축적하고, 상기 스프링(5)의 탄발력을 의해 플런저(3)의 토출 동작을 행하게 하여 위사 도입 노즐에 분사수를 공급하는 물 분사식 직기의 펌프 장치(30)에 있어서, 소정 시기, 특히 상기 스프링(5)의 압축시에 스프링 선재(5a)의 공진을 적극적으로 억제하는 공진 억제 수단을 설치한다. 이 공진 억제 수단은, 예를 들면 스프링(5)의 압축시에 스프링 선재(5a)를 적어도 일부 구속하는 구속 수단으로서의 탄성 부재(12)로 구성되고, 스프링(5)의 선재(5a) 사이에 배치되어 있다. 또, 이 탄성 부재(12)는 스프링(5)의 최대 압축시의 스프링 선재(5a) 간격 이상의 두께를 갖고 있다. 또, 탄성 부재(12) 대신에 스프링의 압축시와 신장시에 유효 권취수를 변경하는 유효 권취수 변경 수단으로서 부등 피치 스프링(40)을 설치하거나, 구획 부재(19)를 설치해도 좋으며, 혹은 스프링 선재에 대해 제동을 부여하는 제동 수단을 설치하도록 해도 좋다.Water that accumulates the force of the spring 5 in accordance with the suction operation of the plunger 3, causes the plunger 3 to be discharged by the elastic force of the spring 5, and supplies water to the weft inlet nozzle. In the pump device 30 of the jet loom, resonance suppression means for actively suppressing the resonance of the spring wire rod 5a is provided at a predetermined time, particularly at the time of compression of the spring 5. This resonance suppression means is comprised by the elastic member 12 as a restraining means which restrains at least one part of the spring wire 5a at the time of the compression of the spring 5, for example, between the wires 5a of the spring 5; It is arranged. Moreover, this elastic member 12 has the thickness more than the space | interval of the spring wire rod 5a at the time of the maximum compression of the spring 5. In place of the elastic member 12, an unequal pitch spring 40 may be provided or a partition member 19 may be provided as an effective winding number changing means for changing the effective winding number at the time of compression and extension of the spring. Braking means for providing braking to the spring wire rod may be provided.
