Definitions
- the invention relates to a hydraulic oil tank for working machines, such as concrete mixers, cranes and the like.
- the present invention aims to provide a hydraulic tank in which the previously required space, weight and effort is avoided.
- the invention is characterized in that the hydraulic oil tank has a substantially parallelepipedic tank housing, which is provided with a Hydrauliköleinlnut to a hydraulic oil cooler, which is arranged in a passage opening of the tank housing together with a fan blower, the hydraulic oil cooler having an outlet for cooled hydraulic oil, via which the hydraulic oil in the hydraulic oil tank and from this via a hydraulic oil filter and a suction port of the tank housing in the hydraulic circuit is removable.
- the tank housing is provided on its upper side with a filter cover, via which a cylindrical filter cartridge can be inserted into the hydraulic oil tank.
- Tank housing equipped with a level indicator and a thermostat, and may also be equipped with a clogging indicator.
- the invention will be explained in more detail below using an exemplary embodiment with reference to the drawings.
- Fig. 1 is a side view of the invention
- FIG. 2 is a rear view
- FIG. 3 is a further side view
- FIG. 4 is a front view
- FIG. 5 is a plan view
- FIG. 6 is a section along the line VI - VI in FIG. 1, FIG.
- Fig. 7 is a section along the line VII-VII in Fig. 1 and Fig. 8 is a section along the line VIII-VIII in Fig. 1st
- the hydraulic oil tank shown in the drawings has a tank housing 1 made of plastic or metal with a closable Hydrauliköleinlnut 2 and connectable to a suction hose, not shown suction port 3 and a level indicator 4.
- a Filter cover 5 is provided and in the area of the tank bottom a drain plug 6.
- a hydraulic oil tank 7, a hydraulic oil cooler 8 and a cartridge-shaped hydraulic oil filter 9 are provided in the housing interior.
- hot, dirty hydraulic oil flows via the hydraulic oil inlet 2 into the hydraulic oil cooler 8.
- the hydraulic oil flows through the cooler and is thereby cooled, whereupon it flows from the hydraulic oil cooler 8 directly into the hydraulic oil tank 7 via a pipe 11.
- the hydraulic oil flows through the interchangeable cartridge-shaped hydraulic oil filter 9, which is attached to an angled Sauganschlußstutzen to the suction port 3, from which the filtered and cooled hydraulic oil exiting the tank housing 1 and returns to the hydraulic circuit.
- a passage opening 1 ' is provided in the tank housing 1, in which an axial fan 10 is installed, which cools the hydraulic oil flowing through also in the passage opening 1' arranged hydraulic oil cooler 8.
- a thermostat 12 is finally installed and not shown screwed hydraulic oil clogging indicator provided.
