Filed: 1961-03-13
Abstract: 986,662. Ventilating vehicles. FIRTH CLEVELAND Ltd. March 13, 1961 [March 12, 1960], No. 9061/61. Heading F4V. A heater-ventilator unit for a vehicle, e.g. a motor car, comprises a housing having an inlet and outlet 2, 3 and contains a transverse flow blower 4 constructed as described in Specification 876,611, a filter 5 and a heater 6. The filter is pivoted about a horizontal axis and normally lies transversely to the air flow but can be moved manually to the position shown if much heating or ventilating air is required. A pivotal flap valve 48 is mounted on the downstream side of the heater 6 and, when in the position shown, forces all the air to by-pass the heater. It can be moved to the position shown dotted to cause the air to pass through the heater. A baffle 17 divides the inlet into two ducts controlled by butterfly valves 32, 33 respectively in a by-pass round the blower and downstream of the blower. When the vehicle is at rest or moving slowly, the valves 32, 33 are respectively closed and open, but as speed increases, a higher ram air pressure is conveyed down tube 25 to a bellows 22 which is expanded to open valve 32 and close valve 33 through a cord 28, the blower being throttled and the ventilating air-flow being derived from movement of the vehicle. The movement of valve 32 is made non-linear by passing the cord round a cam 29. Movement of the bellows may also switch off the blower motor. Heater 6 may be supplied with engine cooling water or by water circulating in a closed system and heated by a burner supplied with air from downstream of the blower. In a modification, Fig. 4, blowers 73 draw air through a filter 71 and arcuate heater 77 and exhaust it through diffuser 87 controlled by flap valve 88. An arcuate baffle 80 pivoted at 79 causes the incoming air either to by-pass the heater or to flow through it. Two blowers are located side by side and discharge into separate chambers downstream of valves 88 and supplying air to different regions of the vehicle interior. Specification 986,663 also is referred to.
