Definitions

the invention relates to a hand pump according to the preamble of the main claim.
Such a hand pump is used to tilt the cab of trucks and is known from a variety of embodiments. It has a changeover valve for tilting or tipping back the cab and, if necessary, an idle position.
For the double-acting hydraulic cylinder it has two hydraulic connections as a return line to the hydraulic cylinder. It is also provided with an actual pump part upstream of the changeover valve.
the invention has for its object to provide a hand pump so that even manual operation can be easily retrofitted.
a hand pump is only designed so that a separate pressure connection and a separate suction connection is provided, to which then Cables can be connected to an electric hydraulic pump with flow and return, whereby a separate valve for switching the tilting direction is not necessary because use is made of the switch valve provided in the hand pump anyway.
the hand pump designated overall by 5, has a changeover valve 7 provided with a handle 6 and two - in the flow direction behind - the actual pump part 8 and two hydraulic connections 9, 10 for the supply and return line to the hydraulic, double-acting cylinder (not shown). Hydraulic fluid is pumped from the actual pump part 8 in the direction of the changeover valve 7 and from there via two right-angled bores and seals to one of the two hydraulic connections (connection 9 in FIG. 2). The other hydraulic connection 10 opens into an annular space (not shown) of the order switching valve, which is always connected via a line 11 (FIG. 1) to a tank 12 containing the hydraulic fluid, which is located in the housing 13 of the hand pump 5.
a changeover valve 7 provided with a handle 6 and two - in the flow direction behind - the actual pump part 8 and two hydraulic connections 9, 10 for the supply and return line to the hydraulic, double-acting cylinder (not shown). Hydraulic fluid is pumped from the actual pump part 8 in the direction of the changeover valve 7 and from there via two right
the tank 12 is also, as shown in FIG. 1, provided with a separate suction port 14, which is closed by a seal 15 and a cap 16 when not in use.
the separate suction port 14 extends outside the housing 13 and is easily accessible from there.
a separate pressure connection 17 is led out of the housing 13, which is connected between the actual pump part 8 and the changeover valve 7 and is preferably provided with a check valve opening towards the changeover valve 7.
