Abstract
A dispensing head for a trigger dispenser includes a frame having a functional zone on which a frame port, a suction outlet port and a dispensing inlet port open. A valve device applied to the functional zone includes a suction shutter and a dispensing shutter that implements a precompression of products before dispensing. The valve device cooperates with a reference plane of the frame to form a precompression chamber upstream of the dispensing inlet port.
