摘要： An anti-blocking braking system for a land vehicle, comprising a pump (42) which actuates a wheel brake (37), whereby said pump removes brake fluid from a brake pressure sensor unit (31) and supplies it to the wheel brake (37). A first valve arrangement (1) in an a non-actuated position (1.1) blocks the connection between the brake pressure sensor unit (31) and an input connection (42e) of said pump (42) and produces a primary fluidic connection (A) when it is in at least one actuated position (1.3). A first electromagnetic valve (50) in a non-actuated position (50.1), produces a connection between an output connector (42a) of said pump (42) and the brake pressure sensor unit (31) and blocks said connection when it is in an actuated (50.2). A second electromagnetic valve (39) in a non-actuated position (39.1) blocks a connection between the wheel brake (37) and the input connection (42e) of the pump (42) and produces said connection when in an actuated position(39.2). A third electromagnetic valve (38) in a non-actuated position produces a connection between the output connection (42a) of the pump (42) and the wheel brake (37) and blocks said connection when it is in an actuated position (38.2). In order to achieve more precise pressure modulation during a pressure maintenance operational phase, the third electromagnetic valve (38) is placed in an actuated position (38.2) during said phase.
