The construction of the RCV pedal is shown in the below drawing. The casing has vertical holes in
which reducing valves are assembled.
The pressure reducing section is composed of the spool (7), spring (5) for setting secondary
pressure, return spring (9), stopper (8), and spring seat (6). The spring for setting the secondary
pressure has been generally so preset that the secondary pressure is 6.3
±

(depending on the type). The spool is pushed against the push rod (13) by the return spring.
When the push rod is pushed down by tilting pedal, the spring seat comes down simultaneously and
changes setting of the secondary pressure spring.
