Valve arrangement for high pressure pumps |
摘要 |
A relief valve for high pressure pumps is described which is characterized by its extremely compact construction and complete reliability against leakage. The relief valve has a valve ball in the bypass path which is pressed by a high and preferably adjustable force against the valve seat, by means of a compression spring which is located entirely in the housing of the unloader. The spigot which acts against the ball in the bypass path is actuated by means of a piston which is acted on by the output pressure over its entire cross-sectional area.
