Ventilation
Ventilation, heating and blowing of a windshield is carried out by the air which is soaked up outside. Interior heating is provided by air heated in the heater radiator, which is included in the engine cooling system. Outside air enters through the grille of the car hood into the air intake box, where it abruptly changes the direction of movement and enters through the hatch, closed by the air intake cover 2, into the casing 5 of the heater radiator (on the diagram of the heater operation is shown by arrows).
The plastic casing 5 of the radiator is fastened on four studs to the bulkhead shield amplifier under the air intake box, which can be accessed under the instrument panel. The radiator casing with the air intake box are sealed with a sealing gasket. Heater radiator 3 is installed in casing 5 and sealed around the perimeter with a rubber gasket. The right tank of the radiator is divided by a rubber partition into two cavities. A discharge pipe 6 and a valve 8 with an inlet pipe 7 are bolted to the tank. The ends of the pipes go into the engine compartment through the bulkhead and are connected by hoses to the engine cooling system. The outlet of the pipes to the engine compartment is sealed with a rubber seal, which is attached to the bulkhead with two bolts.
The air from the radiator 3 enters the guide casing and the casing 14 of the fan. In the center of the plastic guide casing, with the help of spring brackets on two elastic cushions, an electric motor 11 with a fan impeller 9 is installed. Additional resistance is attached to the inner wall of the casing (resistor) 12, which is connected and disconnected to the electric motor circuit by a three-position switch on the instrument panel. An additional resistor provides low and high fan speed.
From the fan casing, air rises through the window of the guide casing into the air duct 1 and then through pipes 33 and rotary deflectors 20 is supplied to the windshield or directly to the passenger compartment. The deflector pipes with the air duct are sealed with rubber seals 34.
An air distribution cover 10 is pivotally mounted on brackets at the bottom of the fan casing, when opened, the air is directed to the passengers' feet through the air duct 13 of the internal ventilation. At the same time, the amount of air entering the deflectors is reduced.
The heater is controlled by a fan motor switch, rotary deflectors and two handles. The upper handle 18 for controlling the heater tap is connected by a flexible rod 4 to the tap lever. The lower handle 17 is connected by a flexible rod 19 to the lever of the cover 2 of the air inlet and regulates the amount of fresh air entering the heater.
The car has an exhaust ventilation system that sucks air out of the passenger compartment. The air passes under the lining of the inner roof side panel on the C-pillars, depresses the rubber valve and exits through the decorative grille on the roof side panel. The valve prevents the penetration of air and the passenger compartment in crosswinds.
Windshield washer
The washer with a screen wiper provides cleaning of a windshield in any conditions of operation of the car without its stop.
The washer includes a pump 30, a tank 32 for liquid, tubes 31, 29, 21 and 26, jets 27.
From the pump, the liquid is supplied to the jets and through the slot in the nozzles 24 it is sprayed onto the glass. The jets consist of a body 23 and an atomizer 24 with a fixing screw 25 and gaskets. The jets are installed in the holes of the windshield panel using elastic plastic bushings 22 on the pump housing.
The jet direction is adjusted by turning the jet body in the plastic sleeve and turning the atomizer 24 after loosening the fixing screw 25.
Until 1980, an electric pump was installed on the VAZ-2103, which is also used on the VAZ-2106.
The foot pump 30 is fixed to the floor of the body. Diaphragm pump. Housing 48 of the pump is plastic, has two fittings. The inlet fitting is connected to the tube 31 with the washer tank 32. The fittings have rubber inlet - 37 and outlet - 50 valves. The valves are held in their seats by brass bushings pressed into the body. Diaphragm 47 cup-shaped, housing 48 and cover 38 are rolled in a steel casing 49, to which the pump mounting plate is welded. On cover 38, a wiper switch and a pump drive are installed. The drive consists of a button 40 with a stem 42 and a return spring. A plate is riveted to the lower end of the rod, which, when the button 40 is pressed, presses on the diaphragm. After releasing the button, the diaphragm returns to its previous shape due to elasticity. The switch consists of a plastic block 45 with two pairs of contacts, one pair is riveted to the top and the other to the bottom of the block. The contacts are closed by movable jumpers riveted to the plastic holder 44. In the normal position of the button 40, the upper pair of contacts is closed, and when the button is pressed, the lower pair is closed. Outside, the pump drive is closed with a rubber boot 41.
Washer pump with rotary electric drive. Pump housing (from below) and electric motor (above) are attached to the washer reservoir cap with three screws. The pump rotor captures the liquid entering through the strainer and delivers it through the tube up to the cap fitting. The rollers of the rotor and the electric motor are connected by a plastic tubular coupling.
