Claim Text:
1. An internal combustion engine cooling system having a cooling water regulator configured in a cooling circuit, said cooling water regulator operable by an engine control in such manner to temporarily wholly interrupt the flow of the cooling water, comprising: a subsidiary branch, a flap element having a first end and a second end and wholly disposed within said subsidiary branch, said second end pivotally connected to said subsidiary branch, a locking lever having a first arm and a second arm, said locking lever pivotally attached at a point intermediate said first arm and said second arm, and an electromagnetic locking apparatus having a core and a spring member, wherein said first arm is magnetically attached to said core against the biasing force of said spring member and said second arm engages said first end of said flap element when said locking lever is in a locked configuration, and wherein said core disengages from said first arm thereby allowing the locking lever to pivot due to the biasing force of said spring member thereby allowing the second arm to disengage said first end of said flap element when said locking lever is in an unlocked configuration, whereby said flap element pivots as a result of the water pressure within said subsidiary branch, and wherein the spring member biases the locking lever in a direction that unlocks the flap element such that the flap element is enabled to move from a closed position to an open position, wherein at least a portion of the spring member encircles at least a portion of the core, and wherein the spring member applies a compressive force onto the first arm.
