Embodiment Construction
[0025] figure 1 A cross-sectional view of a hydraulic device is shown, eg a motion control block 1 designed as a large plate structure and comprising a disk 2 to which an opposing disk 4 is assigned. A one-way valve 6 is inserted in the disc 2, which, in the locked position shown, blocks the hydraulic fluid flow passage between the inlet A and the outlet passage 8 formed in the opposite disc 4, while the one-way valve 6 is in the locked position shown. The open position controls the connection to open the connection.
[0026] The one-way valve 6 includes a locking element 10 which is biased by a cone 12 against a suitably formed valve seat 14 . The locking element 10 is a hollow piston in which the inner bore 16 opens through an inclined channel 18 in an annular chamber 20 formed by a plurality of dimples on the outer circumference of the locking element 10, each of the inclined holes 18 respectively opening to a dimple. The basic structure of such a locking element 10 is d...
