Abstract: PROBLEM TO BE SOLVED: To provide a fluid supply device having the minimum number of leakage passages. SOLUTION: This assembly includes: a housing having a chamber; a main body having a circular seal lip and a fluid channel between a fluid inlet and a fluid outlet; a piston arranged within the main body and the housing and having a first end and a second end; a spring; and a handle. A poppet/diaphragm of the piston includes a non-porous head seated on the seal lip, a thin wall sleeve, and a tong forming a terminal end of the sleeve. The spring presses the head of the poppet/diaphragm to the seal lip. The handle is mounted on the first end of the piston so as to move the piston axially between an open flow position and a closed flow position within the assembly. When the piston moves axially in the assembly, the sleeve of the diaphragm rotates between the opposing piston and the wall of the assembly.
