본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1-3도는 여러 작동위치의 바람직한 실시에에 따른 유압 피스톤펌프의 수직단면도.1-3 are vertical sectional views of a hydraulic piston pump according to a preferred embodiment of the various operating positions.

제4도는 제1도에 도시한 장치의 화살표 A방향의 측면도4 is a side view in the direction of arrow A of the apparatus shown in FIG.

Claims (5)

하우징, 펌프하우징내의 실린더에서 활주가능하게 안내되며 작동유를 각각 함유하는 전방 및 후방체임버로 실린더를 분할하는 작동피스톤, 작동피스톤에 연결되어 외부하중에 따라 작동하도록된 피스톤봉, 작동시 가압작동유를 출구밸브와 압력덕트를 경유하여 전방체임버로 공급하는 동시에 후방체임버에 존재하는 가압작동유를 입구밸브를 경유하여 다른 실린더로 공급하는 펌프하우징내의 다른 실린더에서 이동가능한 펌프피스톤, 전방체임버를 비우기위한 수동작동 가능한 밸브, 및 작동피스톤이 그의 후방 사점위치에 위치될때 후방체임버가 완전히 비워지는 것을 방지하는 억제장치로 구성되는, 수동작동가능한 유압피스톤펌프.An operating piston slidably guided by the cylinder in the housing, the pump housing, and divided into a front and rear chamber containing hydraulic fluid respectively, a piston rod connected to the operating piston to operate according to an external load, and a pressurized hydraulic fluid during operation. A pump piston that can be moved from another cylinder in the pump housing that supplies pressurized hydraulic oil present in the rear chamber to another cylinder via an inlet valve while supplying it to the front chamber via a valve and a pressure duct, and can be manually operated to empty the front chamber. A hydraulically actuated piston pump, comprising a valve and a restraining device that prevents the rear chamber from emptying completely when the actuating piston is positioned at its rear dead center position. 제1항에 있어서, 억제장치를 후방체임버를 향하고 있는 작동피스톤의 정면에 설치함을 특징으로 하는 피스톤 펌프,The piston pump according to claim 1, wherein the suppressor is installed in front of the actuating piston facing the rear chamber. 제1항에 있어서, 억제장치를 후방체임버를 향하고 있는 작동피스톤의 실린더의 정면에 설치함을 특징으로 하는 피스톤펌프.2. The piston pump according to claim 1, wherein the suppressing device is installed in front of the cylinder of the actuating piston facing the rear chamber. 제2항에 있어서, 억제장치의 직경을 작동피스톤의 직경보다 작게 형성시킴을 특징으로 하는 피스톤 펌프.3. The piston pump according to claim 2, wherein the diameter of the suppressor is made smaller than the diameter of the working piston. 제3항에 있어서, 억제장치의 직경을 작동피스톤의 실린더의 정면의 직경보다 작게 형성시킴을 특징으로 하는 피스톤펌프.4. The piston pump according to claim 3, wherein the diameter of the suppressor is made smaller than the diameter of the front face of the cylinder of the working piston. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
