The invention relates to a hand brake valve (100) for actuating a parking brake (700) and/or an auxiliary brake (702) of a vehicle (1000), in particular a commercial vehicle (1002), and to a method for assembling a hand brake valve (100). A hand brake valve (100) includes a valve cartridge (120) including a cartridge locking feature (126), where the valve cartridge (120) is adapted to receive a valve piston arrangement (180) having a valve piston (182) and a valve seat element (136), where the valve seat element (136) is movable in an axial movement (MA) along a valve axis (AV) against a valve stop (124) of the valve cartridge (120). According to the invention, the hand brake valve (100) further comprises: a valve guide element (140) having a guide body (146) adapted to limit an axial movement (MA) of the valve seat element (136), where the valve guide element (140) comprises at least one guide locking feature (142) adapted to form a shape lock (PL) with the cartridge locking feature (126), where the shape lock (PL) is established by a locking movement (ML) of the valve guide element (140) into a locking position (LOP), where the valve guide element (140) has a guide body (146) adapted to limit the axial movement (MA) of the valve seat element (136). And the hand brake valve (100) comprises at least one snap lock element (144) adapted to fix the valve guide element (140) in the locking position (LOP).

    本发明涉及用于促动车辆(1000)、特别是商用车辆(1002)的驻车制动器(700)和/或辅助制动器(702)的手制动阀(100)和组装手制动阀(100)的方法。手制动阀(100)包括:包括筒锁定特征(126)的阀筒(120),其中阀筒(120)适于容纳具有阀活塞(182)和阀座元件(136)的阀活塞装置(180),其中阀座元件(136)可抵靠阀筒(120)的阀止挡(124)在沿着阀轴线(AV)的轴向移动(MA)中移动。根据本发明,手制动阀(100)还包括:具有引导体(146)的阀引导元件(140),其适于限制阀座元件(136)的轴向移动(MA),其中阀引导元件(140)包括至少一个引导锁定特征(142),其适于与筒锁定特征(126)形成形状锁定(PL),其中通过阀引导元件(140)到锁定位置(LOP)的锁定移动(ML)来建立形状锁定(PL),并且手制动阀(100)包括至少一个卡扣锁元件(144),其适于将阀引导元件(140)固定在锁定位置(LOP)。
