A lubricant vane pump for providing a pressurized lubricant for an internal combustion engine includes a pump housing enclosing a pumping cavity comprising a charge zone and a discharge zone. A shiftable control ring envelops the pumping cavity. A pump rotor comprising vanes divides the pumping cavity into pumping chambers. The pump rotor is radially slidable and rotates in the control ring from the charge zone to the discharge zone. A spring chamber comprises a pretensioning element which pushes the control ring to a high pumping volume direction. A control chamber is configured so that a lubricant pressure in the control chamber moves the control ring to a low pumping volume direction against a force of the pretensioning element. A pumping cavity outlet port is connected to the control chamber. A pressure equilibration channel drains the lubricant from the pumping chamber in the discharge zone into the spring chamber.
