高圧ポンプ
Document Type and Number:
Japanese Patent JP2006514195
Kind Code:
A
Abstract:
The high pressure pump has a displaceable control piston (25) guided in a longitudinal bore (24) of a passage (23) in the main piston (6). Fluid in the working chamber (8) acts on one side of the piston and fluid in the discharge chamber (22) on the other. The control piston ensures that the pressure in the discharge chamber increases with that in the working chamber, decompressing the sliding fit between the main piston and the stroke ring (12).
