#CMT# #/CMT# The pressure relief valve has a valve housing (1) with an input (2) and an output (3), where the input and the output are connected over an axially slidable valve element (4) that is received in the valve housing. A hydraulically actuated valve (8) is arranged in a bore (7), whose opening pressure is smaller than the opening pressure of the pressure relief valve. The hydraulically actuated valve is connected with a spring chamber (5) in the opening position of the input. The spring chamber is relieved over a relief bore (12) that is formed in the valve housing. #CMT# : #/CMT# An independent claim is included for a fuel delivery device with a pressure side that is connected with a suction side over a pressure relief valve. #CMT#USE : #/CMT# Pressure relief valve for a fuel delivery device, particularly a feed pump of a fuel injection system for injecting fuel in a combustion chamber of an internal combustion engine (Claimed). #CMT#ADVANTAGE : #/CMT# The pressure relief valve has a valve housing with an input and an output, where the input and the output are connected over an axially slidable valve element that is received in the valve housing, and the hydraulically actuated valve is arranged in a bore, whose opening pressure is smaller than the opening pressure of the pressure relief valve, and thus ensures simple construction and space-saving installation of the pressure relief valve. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a pressure relief valve. 1 : Valve housing 2 : Input 3 : Output 4 : Valve element 5 : Spring chamber 7 : Bore 8 : Hydraulically actuated valve 12 : Relief bore. |
