Abstract: A fluidic diverter valve includes valve element freely disposed within a valve bore. The valve bore has a cross sectional area that varies. As a result, the clearance between the valve element and an inner surface of the valve bore also varies. This variation in cross sectional area, and thus clearance, is such that a force of sufficient magnitude to move the valve element from a seated position is initially applied to the valve element, but the force on the valve element is reduced once it is moved from the seated position. Thus, the impact force upon attaining another seated position is reduced.

Abstract: A diverter valve includes a valve bore having a set of valve seats associated with each fluid outlet port. Each set of valve seats is at least partially separated from one another by a flow channel. The valve seat configuration increases the impact area for the valve element. As a result, the impact force upon seating against the valve seats is reduced. Moreover, by including flow channels between the sets of valve seats, the switching force and performance of the valve element is not adversely affected.

Abstract: The present invention provides anchor tabs at opposite ends of a film member that are anchored to side faces of a door plate of a sliding door.

Also, fluctuations in pressure difference between the inner and outer sides of the anchor tabs are suppressed, and the production of extraneous noise caused by self-excited vibration of the anchor tabs at the ends of the film member is suppressed.

Abstract: According to the present invention, in an air conditioner for a vehicle, when the cool air passage is opened, the sliding door slides so as to incline with respect to the flowing direction of the cool air in such a manner that an end portion of the sliding door at a side of said cool air passage is located at the most air downstream side. That is, when the sliding door is controlled to fully open the cool air passage (i.e., the warm air passage is fully closed), for example, in the maximum cool mode, the sliding door slides while inclining with respect to the flowing cool air. In this operation, the air is blocked from flowing into the warm air passage, and such air is smoothly guided into the cool air by the sliding door, because the sliding door inclines with respect to the flowing direction of cool air, thus increasing the amount of cool air into the passenger compartment.
