Hydraulic vehicle brake system with wheel slip control, and valve for such a brake system

A hydraulic vehicle brake system with wheel slip control, comprising:

• a primary and a secondary circuit,
• a valve interposed between the primary and the secondary circuit said valve including a valve seat member and a valve closure member with a pilot pressure,
• means for automatically permitting an increase of the pilot pressure of the valve closure member acted upon by a valve spring, wherein the pilot pressure is overcome to switch the valve closure member to an open position, at least to such an extent that the valve closure member remains in a closed position during wheel-slip free operation of the brake system, and
• a captivating element which encompasses at least two adjacent coils of the valve spring.
