Anti-locking brake system

Anti-locking brake system, which is set up in particular for traction control and vehicle dynamics control, having

• a pump (42) for actuating a wheel brake (37), which pump removes brake fluid from a brake pressure generating unit (31) and supplies it to the wheel brake (37), and
• a valve arrangement (1), which
• is disposed between the brake pressure generating unit (31) and an input connection (42e) of the pump (42) and takes the form of a 2-connection/3-position valve, which
• in a non-actuated normal position (1.1) blocks the connection between the brake pressure generating unit (31) and the input connection (42e) of the pump (42),
• in a first actuating position (1.2) establishes a secondary flow connection (B) between the brake pressure generating unit (31) and the input connection (42e) of the pump (42), and
• in a second actuating position (1.3) establishes a primary flow connection (A) between the brake pressure generating unit (31) and the input connection (42e) of the pump (42), wherein
• the primary flow connection (A) has a larger flow cross section than the secondary flow connection (B) and
• upon each actuation of the valve arrangement (1) initially only into the secondary flow connection (B) and then the primary flow connection (A) exists, characterized in that during actuation of the valve arrangement (1) the valve arrangement (1) is then, through adjustment of the actuating force, selectively adjustable either into the primary (A) or into the secondary (B) flow connection.
