Abstract:
A valve member is movable with first and second partition member and opens and closes a first pressure chamber with respect to a return passage. The first partition member partitions the first pressure chamber from a second pressure chamber. The second partition member partitions the second pressure chamber from a third pressure chamber. The first, second, and third pressure chambers cause fuel from a fuel flow passage to flow therethrough. A switching unit switches an opening and closing state of the second pressure chamber and the third pressure chamber with respect to the fuel flow passage and the return passage.

Claim (Index 5):
A pressure regulator configured to release fuel from a fuel flow passage into a fuel tank through a return passage to regulate a fuel pressure in the fuel flow passage, the fuel flow passage configured to cause fuel pumped by a fuel pump from a fuel tank to flow toward an internal combustion engine, the pressure regulator comprising:\n a first pressure chamber configured to cause fuel branched from the fuel flow passage to flow therethrough; a second pressure chamber adjacent to the first pressure chamber and at atmospheric pressure; a third pressure chamber adjacent to the second pressure chamber and configured to cause fuel branched from the fuel flow passage to flow therethrough; a valve member configured to open and close the first pressure chamber with respect to the return passage; a first partition member configured to move with the valve member in a state where the first partition member and the second partition member are partitioned from each other; a second partition member configured to move with the valve member and the first partition member in a state where the second pressure chamber and the third pressure chamber are partitioned from each other; and a switching unit configured to switch an opening and closing state of the second pressure chamber with respect to the fuel flow passage and an opening and closing state of the second pressure chamber with respect to the return passage in an open-close relationship opposite to each other.
