A flushing arrangement for a WC, comprising a toilet bowl which has an inlet and an outlet, there between a U-bend, and pulse generating elements for generating a pulse with which water which is present in the U-bend and forms an air trap is accelerated, for a flushing operation, in the direction of the outlet. The pulse generating elements are arranged in the U-bend and have a plurality of nozzles, or at least one annular gap extending in the circumferential direction of the U-bend. The nozzles or the at least one annular gap generate, in the water in each case, a flow which is directed substantially towards the outlet. The nozzles or the at least one annular gap are arranged directly upstream of an ascending region or in an ascending region of the U-bend.
