Abstract

An integrated high pressure pump with a cylinder block may include the cylinder block having a crank shaft positioned therein and a pump hole having a predetermined diameter formed in a direction perpendicular to a length direction of the crank shaft, and a tappet guide part seated to be inserted along the pump hole to connect the cylinder block and a high pressure pump device to each other, in which the high pressure pump device is provided with a tappet moved along an inner portion of the tappet guide part, such that turning force of the crank shaft is directly transferred thereto.

First claim

What is claimed is:

1 . An integrated high pressure pump with a cylinder block, the integrated high pressure pump comprising:
the cylinder block including a crank shaft positioned therein and a pump hole having a predetermined diameter formed in a direction perpendicular to a length direction of the crank shaft; and a tappet guide part seated to be inserted along the pump hole and connecting the cylinder block and a high pressure pump device to each other, wherein the high pressure pump device is provided with a tappet movable along an inner portion of the tappet guide part, such that turning force of the crank shaft is directly transferred thereto.

2 . The integrated high pressure pump of claim 1 , wherein the crank shaft includes a cam installed at one point on an outer peripheral surface thereof, and
the tappet is in contact with an outer peripheral surface of the cam and moveable back and forth by a turn of the crank shaft.

3 . The integrated high pressure pump of claim 2 , wherein the tappet guide part includes a vertical flange extending a predetermined length in a direction of the cam and having a guide hole formed therein, the tappet being moveable through the guide hole, and a horizontal flange extending from the vertical flange and coupled to an outer portion of the cylinder block through a bolt.

4 . The integrated high pressure pump of claim 3 , wherein the high pressure pump device is coupled to the horizontal flange through the bolt, and has the tappet formed therein, the tappet being moved along the guide hole formed in the vertical flange, and an inlet valve formed therein, wherein the inlet valve supplies fuel into the high pressure pump device and is opened and closed by a separate controller.
