Abstract (en)
[origin: DE102008059436B3] The valve (20) has standard contacts (A, B, P, T) formed at a valve housing (21). An internal annular channel (V) is formed in the housing and is connected with the contact (B) in a control position of a control piston (26). The channel is connected with an annular space (23) by an internal bridge (30) formed in the housing. A recess (28) produces connection of the contacts (A, T), where a dimension of the recess is twice larger than another recess (28a), which connects the contacts (P, A) and/or the contacts (P, B) and/or the contact (B) and the channel in the control position of the piston.
