摘要

The invention relates to a hydraulic pumping unit for feeding the hydraulic tilting cylinder(s) with a vehicle having a tilting cab, comprising a housing (1), a displacement body mounted for movement in a pumping chamber within said housing (1), a control valve having a bore in connection with said pumping chamber and a control valve body (2) within said bore, said control valve body (2) being provided - at an end (3) projecting beyond said housing (1) - with a handle by means of which the control valve body (2) may be turned between at least two positions operative to tilt the cab from the drive position and to tilt the cab back into the drive position of the vehicle respectively. In accordance with the invention the handle comprises an inner part (A) that is fixedly connected with the control valve body, and an outer part (B) which is normally enclosing said inner part (A) in a free rotating manner but is mounted to be coupled with said inner part by means of a key-operated lock cylinder (24), said outer part (B) forming the proper handle.
