CONTROL VALVE FOR A DEVICE FOR VARIABLY ADJUSTING THE CONTROL TIMES OF GAS-EXCHANGE VALVES OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a control valve (30) for a device (11) for variably adjusting the control times of gas-exchange valves (9, 10) of an internal combustion engine (1), having a valve housing (33) and a control piston (34), with the valve housing (33) having an axial cavity (35), with a dividing element (36) being arranged in the cavity (35), which dividing element (36) divides said cavity (35) into two partial Spaces (37, 38) and hydraulically seals said partial Spaces off from one another, with the dividing element (36) being produced separately from the valve housing (33) and being positionally fixedly fastened in the cavity (35) of said valve housing (35), with the first partial space (37) holding the control piston (34), and with a supply connection (P) being formed in the region of the first partial space (37), with the second partial space (38) having at least one first opening (43) via which pressure medium can be supplied to said sec- ond partial space (38) by a pressure medium pump (46), and with the second partial space (38) having at least one second opening (44), by means of which the second partial space (38) communicates with the supply connection (P).
