<p><P>PROBLEM TO BE SOLVED: To develop a pressure limiting valve by general technology to improve its usability by structurally simplifying the design of the pressure limiting valve, and manufacturing and operating the same with high cost performance. <P>SOLUTION: This pressure limiting valve comprises a valve housing 1 for a medium as the fluid receiving system pressure, and further has an inlet passage 3 and an outlet passage 4 communicated with the inlet passage 3 for the medium. A flow rate of the medium can be adjusted by a valve element 5 movable in the axial direction to be substantially communicated with an energy accumulating device 2 and interacted with a valve seat 6. In this pressure limiting valve, a piston 7 coaxially adjacent to the valve element 5 shares borders with a throttle gap 7a at its outer side face, and the throttle gap is communicated with the inlet passage 3, and being directly or indirectly pressed by the energy accumulating device 2. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
