Abstract
Official abstract text for this publication.
A pump cover for a fuel pump is located at a position lateral to the fuel pump. The fuel pump is disposed on a cylinder head of an engine. The pump cover includes a plate and a rib. The plate is fixed to a side surface of the engine. The plate extends to a position lateral to the fuel pump disposed on the cylinder head. The rib protrudes from the plate, and is located superjacent to a pump mounting surface defined on the cylinder head.
First claim
Opening claim text (preview).
What is claimed is: 1. A pump cover for a fuel pump, the pump cover comprising: a plate fixed to a side surface of an engine, the plate extending to a position lateral to the fuel pump disposed on a cylinder head of the engine; and a rib that protrudes from the plate, wherein the fuel pump is disposed on an upper surface of the cylinder head in a vehicle-height direction, and the pump cover is located at a position lateral to the fuel pump, the rib is located superjacent to a pump mounting surface, and the pump mounting surface is defined on and above the cylinder head and the rib is positioned between the fuel pump and the plate such that the fuel pump is not interposed between surfaces of the rib and the cylinder head that face each other. 2. The pump cover according to claim 1 , wherein the pump cover includes a plurality of the ribs. 3. The pump cover according to claim 2 , wherein: the number of the ribs is two; and the two ribs are provided such that the fuel pump is interposed between the two ribs. 4. The pump cover according to claim 1 , wherein the rib is configured to extend from the pump mounting surface toward an upper end of the plate. 5. The pump cover according to claim 4 , wherein: a protrusion width of the rib, by which the rib protrudes from the plate, is greatest at a portion facing the pump mounting surface; and the protrusion width is gradually decreased in an upward direction from the pump mounting surface.
