I just went out and looked at mine. It looks to me like your nozzle is not pulled out far enough and is pointed up a little. Mine is pulled out far enough so there is a short flat area on the nozzle behind the taper which shows on your picture. It think this is just an adjustment issue with the nozzle where the water comes out. I do not think it is a malfunction or an issue of too much pressure. At least that is my take on the situation.
