Non-flowing pilot valve

A pilot valve (10) comprising,

• a valve body (12), and a sense chamber (26), an exhaust-line chamber (34) and a dome-line chamber (32) defined in said valve body (12), said exhaust-line chamber (34) being axially positioned between said sense chamber (26) and said dome-line chamber (32),
• a sense piston (16) having a foot (20), a neck (22) and a head (18), with said head (18) disposed in and slidable with respect to said sense chamber (26), with said foot disposed below said exhaust-line chamber (34) and said dome-line chamber (32), said sense piston (16) having an axial passage (24) from a supply inlet (19) of said foot (20) to a top radial passage (28), which opens to said sense chamber (26), and a lower radial passage (30),
• a set spring (80) coupled between said body (12) and said head (18) which is arranged and designed to provide a downward force to said head (18) representative of set pressure,
• a feedback sleeve (40) disposed about said neck (22), said feedback sleeve (40) being resiliently coupled to said sense piston;
• said feedback sleeve (40) having a lower end with a top annular shoulder (48) and a bottom annular shoulder (50),
• said body (12) carrying an annular pop seal (52) at an axial position between said dome-line chamber (32) and said exhaust-line chamber (34),
• said foot (20) carrying an annular reseat seal (54) at an axial position beneath said dome-line chamber (32),
• said annular pop seal (52) being arranged and designed in cooperation with said top annular shoulder (48) of said feedback sleeve (40) to open or to close fluid communication between said dome-line chamber (32) and said exhaust-line chamber (34), and
• said annular reseat seal (54) being arranged and designed in cooperation with said bottom annular shoulder (46) to open or to close fluid communication between said lower radial passage (30) and dome-line chamber (32).
