摘要
A mixing apparatus for mixing components that interact chemically, preferably polyurethane-forming components, the apparatus including a control plunger disposed within a housing and movable along a mixing chamber between opposing inlet and return ports, the control plunger having along its wall surface return grooves for connecting the inlet ports to the return ports when the plunger is in a position blocking communication between the inlet ports and the mixing chamber wherein a wall surface portion of the control plunger which in the closing position of the plunger is disposed intermediate the return ports is provided with discrete recesses which mutually overlap in the direction of movement of the control plunger.
