Fuel pump |
摘要 |
A fuel pump capable of using the pump efficiency most efficiently without reducing the useful service life is provided. A relatively large clearance allowing for the expected amount of wear is ensured in a region where the flow passage groove pressure is low. In a region where the flow passage groove pressure is high, it is unnecessary to allow for the wear. Therefore, the clearance is set relatively small.
