Abstract

본 발명은 펌핑중인 일정 체적의 작동매체 유동을 발생시키기 위한 유압펌프로서, 상기 작동매체를 공급하기 위한 흡입구와 상기 작동매체를 배출하기 위한 배출구를 구비한 하우징을 포함하고 있는 유압펌프에 있어서, 상기 작동매체의 추가의 유동(작동매체의 냉각유동)을 유입 또는 배출하기 위한 배출구를 더 포함하고 있는 것을 특징으로 하는 유압펌프에 관한 것이다.The present invention provides a hydraulic pump for generating a constant volume working medium flow during pumping, the hydraulic pump including a housing having an inlet for supplying the working medium and an outlet for discharging the working medium, Further comprising an outlet for introducing or discharging an additional flow of the working medium (cooling flow of the working medium).

Description

일정 체적의 오일유동을 송출하는 유압펌프Hydraulic pump for sending a constant volume of oil flow

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 본 발명에 따른 내부 기어식 기어펌프의 축방향에 수직인 단면의 개략도, 제2도 및 제3도는 흡입관과 접속하여 냉각오일을 유동시키는 유압펌프내에 냉각오일이 주입되는 상태를 도시한 개략도, 제4도 및 제5도는 냉각오일이 유압펌프 내에 주입되어 가열된 오일이 유압펌프로부터 배출되는 상태를 도시한 개략도.FIG. 1 is a schematic view of a section perpendicular to the axial direction of an internal gear type gear pump according to the present invention, FIG. 2 and FIG. 3 show a state in which cooling oil is injected into a hydraulic pump connected to a suction pipe, Figures 4, 5 and 5 are schematic views showing a state in which the cooling oil is injected into the hydraulic pump and the heated oil is discharged from the hydraulic pump.
