Abstract

본 발명은 일정유량 토출용 증압기를 개시한다. 본 발명은 유압펌프, 유압모터, 공급유로, 제1제어수단 및 제2제어수단을 포함한다. 유압펌프는 유입되는 유압을 펌핑하여 토출유로를 통하여 유압을 토출한다. 유압모터는 유입되는 유압에 의하여 구동되고 유압펌프에 의하여 토출되는 유압을 증압시키도록 유압펌프를 구동시킨다. 공급유로는 유압펌프와 유압모터에 유압을 공급시킨다. 제1제어수단은 공급유로를 개폐시키고, 제2제어수단은 토출유로에서 토출된 유압이 설정된 유압보다 큰 경우에 제1제어수단이 공급유로를 폐쇄시키도록 제1제어수단을 작동시키는 것이 특징이다. 본 발명에 따르면, 토출유로의 압력이 설정된 압력보다 큰 경우에 제1제어수단과 제2제어수단에 의하여 공급유로는 차단되어 설정된 압력보다 크게 증압되는 것을 방지할 수 효과가 있다. 이로 인하여, 본 발명은 증압기에 연결된 기기의 고장 및 파손을 방지할 수 있는 효과가 있다. 또한, 본 발명은 증압뿐 아니라 유량을 연속적으로 일정하게 토출할 수 있으므로, 유압모터나 유압실린더를 연속적으로 동작시키는 기존 설비에 적용할 수 있는 효과가 있다.
