<p>A milking apparatus that is used to extract milk from dairy animals includes a vacuum source, a milking liner cooperating with a shell to define a pulsatio n chamber; and a pulsator in fluid communication with the pulsation chamber and the vacuum source. The pulsator is configured to produce at least a four-phase milking cycle in the milking liner with the cycle including at least an A phase and a C phase. Th e A phase is wherein the liner is changed from a closed configuration to an open configuration during which the pulsator provides fluid communication between the pulsation chambe r and the vacuum source. The C phase is wherein the liner is changed from an open configuration to a closed configuration during which the pulsator allows atmospheric air to flow into the pulsation chamber. A restrictor is disposed in the path of the fluid communication between the pulsator and the pulsation chamber with the restrictor slowing the C phase compared to the A phase.</p>
