Abstract
A leak recovery groove is formed in a slide clearance between a slidable surface of a cylinder body and a slidable surface of a plunger to recover leaked fuel, which is leaked from a pressurizing chamber. A leak recovery groove direct communication passage is branched from a supply passage, which supplies fuel to the pressurizing chamber, and is connected to the leak recovery groove without passing through the pressurizing chamber to supply the fuel from the supply passage to the leak recovery groove.
