Patent number: 4802457Abstract: In a convention throttle-controlled internal combustion engine (1, 2) equipped with a supercharger which has the form of a compressor (10) provided with screw rotors (14, 15) arranged in a compression chamber, the supercharger is inactive at part engine loads. Since the engine normally operates at part loads for about 95% of its running time, efficiency is correspondingly poor. This drawback is overcome with the arrangement according to the invention in which the screw compressor (10) is provided on the inlet side (20) thereof with a capacity regulating device (22) which is operated by a gas pedal, or accelerator, and which when the engine is only partially loaded, is adjusted to a corresponding position in which the compressor (10) operates as an expander (3) of variable throttle effect on the engine inlet side (3) and transmits power to the engine, thereby replacing the conventional gas throttle.Type: GrantFiled: May 14, 1987Date of Patent: February 7, 1989Assignee: Svenska Rotor Maskiner ABInventor: Johnny Oscarsson

Patent number: 4783962Abstract: Vapor guard systems which prevent vapors from reaching a servomotor from a power source for the servomotor. One embodiment uses a control valve which directs such vapors to a vapor trap filter under conditions where vapor flow may be toward the servomotor, and operates to permit purging of the vapor trap filter when there is flow only away from the servomotor. Another embodiment uses an in-line vapor trap filter and a vapor trap canister, normally used to trap fuel vapors from a vehicle fuel tank, to trap fuel vapors from the power source. Both the in-line vapor trap filter and the canister are purged of adsorber vapors where the power source is operating.Type: GrantFiled: June 25, 1986Date of Patent: November 15, 1988Assignee: General Motors CoporationInventor: John R.

Patent number: 4439983Abstract: A four-cycle internal combustion engine is provided with apparatus comprising a turbine in the inlet air flow path and an extracting compressor in the exhaust gas path. Where the internal combustion engine is an automobile engine and is operating under normal cruising conditions, the manifold inlet pressure is substantially less than atmospheric pressure and incoming air drives the inlet turbine to in turn drive the compressor. The arrangement is such that the inlet air is isentropically expanded while the exhaust gas back pressure is decreased. As a consequence, the energy of compression is reduced and the overall operating temperature of the internal combustion cycle is lowered with the result that more power is delivered for a given quantity of fuel.Type: GrantFiled: November 9, 1981Date of Patent: April 3, 1984Inventor: David C.

Patent number: 4428195Abstract: A rotary vacuum pump is proposed, having a rotor with vanes which rotates eccentrically within a housing bore. Each vane is coupled with a body which is ineffective at relatively low pump rpm; however, at higher rpm, the body engages the vane in such a manner that it removes the vane from its track within the housing bore.In this manner, an rpm-dependent shutoff device is created for the pump. In cooperation with the furnishing of underpressure as an auxiliary pressure in motor vehicles, the pump is used to supplement the underpressure which prevails when the internal combustion engine is at low, idling rpm; this prevailing underpressure is at a very low pressure level, and so when it is thus supplemented there is sufficient auxiliary vacuum force available over the entire rpm range.Type: GrantFiled: April 22, 1981Date of Patent: January 31, 1984Assignee: Robert Bosch GmbHInventors: Ernst Linder, Helmut Rembold, Walter Teegen

Patent number: 4380418Abstract: An aspirator using positive pressure from a suitable source generates a vacuum pressure when the primary source of vacuum pressure, typically the engine intake manifold, prodcuces insufficient vacuum pressure to operate a device such as a road speed control servomotor. The aspirator assembly is connected to the source of positive pressure and the engine intake manifold as well as to atmosphere and to the device to be operated by vacuum power. When there is sufficient intake manifold vacuum pressure for the desired purpose, there is no flow through the aspirator and the engine intake manifold supplies all of the vacuum needs of the servomotor. When aspirator vacuum pressure is required due to insufficient manifold vacuum pressure, the aspirator is opened to generate aspirated vacuum pressure and the connection between the servomotor and manifold vacuum is closed. The aspirated air is delivered to the engine intake manifold.Type: GrantFiled: February 25, 1981Date of Patent: April 19, 1983Assignee: General Motors CorporationInventors: Daniel A.

Patent number: 4328669Abstract: A vehicle vacuum power system which insures sufficient vacuum power to operate a vacuum brake booster and a vacuum operated road speed control system. Because of the low vacuum, high flow rate needs of a cruise control system, the cruise control is connected directly to the engine manifold through a check valve. A small orifice from the vacuum pump in parallel with engine manifold vacuum provides sufficient vacuum for the cruise control when the manifold vacuum is not sufficient. The vacuum pump is in series with manifold vacuum and is operated in response to a pressure switch which allows the pump to run only when brake booster vacuum is low. Manifold vacuum is sufficient most of the time, but the orifice to the cruise control tends to cause a fast loss of brake booster vacuum, causing the vacuum pump to run when it is not actually needed. The vacuum regulator shuts off the flow through the orifice when it is not needed, considerably reducing the pump operational time.Type: GrantFiled: February 15, 1980Date of Patent: May 11, 1982Assignee: General Motors CorporationInventor: Dewey F.

Patent number: 4178756Abstract: A vacuum union having a tubular body adapted for transmitting a vacuum signal from an intake pipe of an internal combustion engine of a vehicle to a vacuum-operated brake booster of a vehicle brake device, and a branch pipe adapted for transmitting a vacuum signal from the tubular body to other vacuum-operated engine controlling devices. An orifice for restricting the level of the vacuum signal, to be transmitted to the brake booster, is located downstream of a branch pipe with respect to the intake pipe. Therefore, a drop in the vacuum level is effectively decreased for maintaining the proper operation of the brake device, even if the controlling devices are damaged, thereby causing the branch pipe to be opened to the atmosphere.Type: GrantFiled: July 14, 1977Date of Patent: December 18, 1979Assignee: Toyota Jidosha Kogyo Kabushiki KaishaInventors: Eiji Adachi, Juichi Shibatani, Sadayoshi Ito

Patent number: 4171618Abstract: A motor is provided of the piston or diaphragm type in which vacuum is constantly applied to one side of a piston or the like and air under pressure is constantly applied to the opposite side to drive the piston through a stroke. The vacuum and pressurized air may be obtained from sources outside the motor. A valve mechanism driven by the motor reverses the application of vacuum and air pressure when the piston reaches each end of its stroke so that power is continuously applied to both sides of the piston during both forward and reverse movement thereof. Different pistons are arranged out of phase with one another to provide a smooth flow of mechanical power. In one version, the motor drives an air pump having a vacuum inlet and an air pressure outlet, and by connecting such inlet and outlet to the valve mechanism, the motor will drive a load as well as itself. In another version, the motor has an internal combustion apparatus incorporated therewith.Type: GrantFiled: June 1, 1977Date of Patent: October 23, 1979Inventor: Karl M. Aegerter

Patent number: 4109464Abstract: An activated charcoal filter is placed in the vacuum conduit between a brake booster and the point where the conduit is connected to an engine to tap intake vacuum for booster power. When for any reason fuel vapor from the engine tends to flow toward the brake booster the charcoal of the filter adsorbs the fuel vapor. When flow of air returns to the normal flow direction, from the booster to the engine, the fuel vapors are desorbed and returned to the engine. Thus the filter has a self-purging action. This effectively prevents condensed fuel vapor from adversely affecting elements of the booster such as the diaphragm when under some particular circumstances and in certain installations fuel vapor would otherwise be introduced into the booster and condensed.Type: GrantFiled: June 9, 1977Date of Patent: August 29, 1978Assignee: General Motors CorporationInventor: Warren A.
