Valve arrangement, particularly for controlling flow in vane pump, has valve piston that is axially adjusted against force of spring in valve bore, where axial section of surface of valve bore is formed in concave manner

摘要

The valve arrangement (17) has a valve piston (23) that is axially adjusted against force of a spring (31) in a valve bore (21). An axial section of a surface of the valve bore is formed in the pressure-free operating condition of the valve arrangement in a concave manner.
