Abstract
Provided is a variable displacement vane pump with a control slide and a first and second control chambers. Also, the pump has a control system for controlling delivery of pressurized lubricant to the chambers. The control system includes a control device configured for movement between at least a first control position and a second control position. The control device may include its own housing and/or include discs configured for relative movement. The pivot pin may include grooves for delivering a flow from the outlet to the control system. In the first control position, pressurized lubricant is delivered to the first control chamber and the second control chamber is vented, which increases the output flow of the pump. In the second control position, pressurized lubricant is delivered to the second control chamber and the first control chamber is vented, which decreases the output flow of the pump.
