Abstract: A door closer for a top hung sliding door has a buffer mechanism and a trolley hanger. The buffer mechanism includes a stationary base, a sliding block, a hook, two buffers and two resilient members. The sliding block is slidably mounted on the stationary base. The hook is pivotally mounted on the sliding block. The buffers are mounted on the stationary base and each buffer has a piston rod secured to the sliding block. The resilient members are mounted on the stationary base and each resilient member has one end secured to the sliding block. The trolley hanger has at least one engaging recess selectively engaging the hook. Therefore, the buffers can provide a buffering force and the resilient members can release a resilient force to reduce a moving speed of a door panel.
