摘要： PURPOSE:To prevent clogging of a condenser even in the case of the condenser for an air conditioner to be used under severe conditions like a construction site, to provide easiness of maintenance and to prevent damage of a heat radiating fin in the case of an operation. CONSTITUTION:A condenser 1 is of a parallel type in which many refrigerant passages 2 are disposed in parallel and flat heat radiating fins 3 without cutting and erecting are provided between the passages 2. Frames 4 are provided at both right and left sides of the condenser 1, and dustproof filters 5, 6 are detachably mounted at front and rear surfaces of the condenser 1 through the frames 4.

摘要： PURPOSE:To simultaneously perform liquid-tight connection of pipes and liquid- tight mounting to a vehicle body so as to improve wiring workability by connecting piping inside and outside the cabin of an automobile to each other through metal plates covered with resilient members, and connecting them to the body. CONSTITUTION:Connectors 10, 11 are fitted to the respective ends of pipes 6b, 7b outside the cabin of automobile through which low and high pressure coolants flow. A first metal plate 13 is inserted into the center of grommet 12 made of resilient material, while pipes 6a, 7a inside the cabin through which pipes low and high pressure coolants flow are fitted to this metal plate 13. The pipes 6b, 7b outside the cabin are fitted through O rings 14, 15 to the pipes 6a, 7a. Connectors 10, 11 are connected through bolts 18, 19 to the threaded holes 16, 17 formed at the grommet 12 and the first metal plate 13. The grommet 12 is fixed to the body 9.

摘要： PURPOSE:To reduce the size of a door device for air intake by a method wherein a slide door is mounted on a case, having an opening part for air intake, in a manner that it is rotationally slid horizontally to the opening part around one end of a shaft. CONSTITUTION:A door 3 is mounted on a case 1, having an opening part 2 for air intake, such that it is rotationally slid horizontally to the opening part 2 around a shaft 5. The door 3 is rotationally slid within a given range through operation of a wire to open and close the opening part 2. The door 3 is pushed up against the spring force of a spring 7 by means of a spherical protrusion part 3d, formed thereon, during rotational slide and rotationally slid in a state to levitate from the wall surface of the case 1 to prevent wear of an air seal 4 mounted on the door 3. When the door 3 is opened to a given opening position, the spherical protrusion part 3d is fitted in a spherical recessed part 1d formed in the wall surface of the case 1 and brought into adhesion to the wall surface of the case 1 through the spring force of the spring 7.

摘要： PURPOSE:To protect the compressor without impairing the cooling performance by causing the compressor operation to be stopped for a prescribed period of time at the time when a pressure sensor has sensed extreme lowering in level of the compressor suction pressure at a low level of cooling and re-operating the compressor after passage of the prescribed period of time. CONSTITUTION:During the engine revolution, when an electromagnetic clutch 8 is excited, a compressor operates with the result that the refrigerant is caused to flow from a condenser 2 into an evaporator 6 through suction and compression thereof. As a result, cooled air is sent into the vehicle compartment by means of a fan 5. During this operation, the suction pressure in the compressor 1 is sensed by a protector 9. And if a condition in which this suction pressure is below a prescribed level continues for a prescribed period of time, the electromagnetic clutch 8 is stopped from excitation to stop the operation of the compressor 1. When another prescribed period of time has lapsed, the electromagnetic clutch 8 is re-excited through performance of a timer function of the protector 9, thereby operating the compressor 1 again. The protector 9 is composed of a pressure sensor 12 and a timer 13, the pressure sensor 12 being connected, via a capillary tube 11, to a low pressure piping 10 for connecting the evaporator 6 and a suction port of the compressor 1.

摘要： PURPOSE:To improve mounting operativity of a pair of brackets with sealing materials adhered on the insides thereof by forming one of the brackets with a hook member and forming the other with two holes and a projection, so that, when they are connected, the hook, holes and projection will constitute a hinge. CONSTITUTION:In order to connect a band U11 and a band L21, a hook member 15 of the band U11 is inserted into a hole 25 of the band L21, with the extreme end of the hook member 15 further inserted into a hole 26. Thus, a hinge is constituted, and a projection 27 cooperates with the pressing force of the band U11 and a seal material 22 of the band L21 against the hook member 15 caused by the hinge to maintain the band U11 and the band L21 in a fixedly connected condition. thus constructed, improved mounting operability is assured.
