摘要

The carriage (1) has a lubricating device (3) for delivery of lubricant, where the lubricating device includes a micropump for pumping the lubricant. The micropump is connected to a lubricant reservoir provided at the carriage. The micropump is designed as a piezoelectric diaphragm pump, which includes a pumping chamber and a valve unit. The pumping chamber is limited by a piezoelectric diaphragm. The valve unit is connected to the pumping chamber, where the valve unit is provided with an inlet valve and an outlet valve.
