Abstract: An air conditioner of a vehicle having a selectively controlled conditioned air blowing outlet system using a shift actuator (20) equipped with a number of negative pressure supplying ports (a, b, c, d), in which selection of the operation mode of the conditioner is represented by the supply of a negative pressure signal to any one of the supplying ports, which causes displacement of a piston (31) of the shift actuator (20). The displacement is conveyed to selected one or more of doors provided at the outlets via a link mechanism to control the outlets according to a predetermined program.

Abstract: The present invention relates to a two position valve having a cam and a cam follower mechanism for holding the valve element in either of its two operative positions, depending on the operation of a push button switch arrangement cooperating with the valve so that the valve shifts between positions in response to pushing the switch. The cam takes the form of an arrowhead shaped groove having first and second apex portions in which the cam follower, a spring loaded pin, traces. The groove is formed with a step at one apex to prevent the pin from reversing its trace and to ensure its oneway tracing about the groove.

Abstract: An intake control system comprising a mode selector which receives a first control pressure and a second control pressure, and, according to the temperature inside and outside the vehicle, adapted to supply selectively a plurality of different combinations of the first and second control pressures to a pressure activated actuator to switch an air intake system between at least an outside air position and a recirculating air position. An air intake changeover switch receives the pressure output by an air control switch, a first reference pressure and a second reference pressure, and supplies a certain combination thereof as the first and second control pressures, when operated, to the mode selector, thereby causing the actuator to switch the air intake system to the recirculating air position, irrespective of the switching state of the mode selector.

Abstract: An air outlet device in a vehicle with an air conditioner comprises a duct which is disposed at the ceiling of the passenger compartment of the vehicle and communicates with the air conditioner. The duct is provided with a first set of air outlets and a second set of air outlets which are located downstream of the first set of air outlets. Within the duct, flow restriction means is disposed at a position downstream of the first set of air outlets and at the same time upstream of the second set of air outlets for restricting the flow rate of air admitted to the second set of air outlets. The first set of air outlets are adjustable to blow toward or away from a passenger of the vehicle. The second set of air outlets are fixed to blow in one direction and adapted to effect mild recirculation of air throughout the passenger compartment.
