1. A guide sleeve for guiding a collar of a relay valve for an electropneumatic modulator for a brake system for a vehicle, comprising:
a guide section couple-able to a counterpart guide section of the collar of the relay valve for the electropneumatic modulator for guiding the collar along the guide section;
a holding section to fasten the guide sleeve in a positively locking manner in a housing of the relay valve;
wherein the electropneumatic modulator includes:
a reservoir connection for a supply of compressed air from a reservoir;
a pneumatic control inlet for the supply of compressed air from the reservoir in response to a pneumatic control signal; and
a brake outlet for outputting a brake pressure to a wheel brake device,
wherein a relay piston and the guide sleeve device are received one above the other in a receiving chamber of a housing, wherein the brake outlet and the reservoir open into the receiving chamber,
wherein the relay valve is configured to open or close a fluidic connection between the reservoir connection and the brake outlet by a movement of the relay piston,
wherein the receiving chamber includes a control chamber section which, controlled by the electrical control signal, is charge-able with supplied compressed air to effect a switching movement of the relay piston,
wherein the guide sleeve is received in or on the relay valve, and the guide sleeve is configured to guide the collar of the relay valve and/or fasten the collar in the housing, wherein the guide section is couplable to or in a counterpart guide section of the collar of the relay valve for guiding the collar along the guide section, and wherein a collar spring is braced between the collar and the guide section.
