Claims (1)

1대의 원동기로서 구동되는 유압펌프에, 유압캠프의 입력 마력을 제한하는 레귤레이타를 비치한 것에 있어서, 이 레귤레이타의 스풀의 일단에 단붙이 피스턴의 대구경측을 맞대여 스풀타단의 가압기구와 대향시킴과 동시, 이 단붙이 피스턴의 2개의 단붙이부와 하우징의 사이에 2개의 유실을 설치하여, 한쪽의 유실에 자기의 펌프토출압력을 유도하고, 다른쪽의 유실에 원동기의 설정 정격회전수와 원동기의 실제 회전수와의 비교검출치에 따르는 유압력을 유도하게 함을 특징으로 하는 유압펌프의 입력제어 장치.The hydraulic pump driven as one prime mover has a regulator for limiting the input horsepower of the hydraulic camp, and the large diameter side of the piston is stepped against one end of the spool of the regulator, and At the same time, two oil chambers are installed between the two end portions of the piston with this stage and the housing, inducing one's pump discharge pressure in one oil chamber, and setting the rated rotation of the prime mover in the other oil chamber. An input control device for a hydraulic pump, characterized in that to guide the hydraulic force according to the detection value of the number and the actual rotational speed of the prime mover. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
