Modular valve assembly for a vacuum booster

[0034] The exemplary first embodiment of the modular valve assembly 10 also includes a floating control valve (FCV) support 28. The modular control valve 10 is retained and positioned within the power piston 12 by an air valve retaining clip 13, and the FCV support 28 in the same manner as described above, with regard to the prior modular valve assembly 156.

[0035] In the first exemplary embodiment, shown in FIGS. 4-10, the air valve 14 and spring seat 22 are attached directly to one another by a snap connection 18. The air valve 14 includes an annular, v-shaped, air valve seat 23 for sealing engagement with the inner periphery of one end of the floating control valve 26, and a first portion 16 of the snap connection 18, extending from the air valve seat 14. The spring seat 22 includes a second portion 24 of the snap connection 18, extending from the spring seat 22. The second portion 24 of the snap connection 18 is adapted for engaging the first portion 16 of the snap connection 18, t
