ELECTRIC MOTOR-DRIVEN IMPELLER-TYPE AIR PUMP

An electrically operated air pump for supplying air to the exhaust system of an internal combustion engine having a central mounting plate which is integral with the electric motor assembly. The armature shaft of the electric motor drives an impeller within a working chamber defined by an impeller housing and one side of the mounting plate. A silencer housing encloses the motor assembly and contains an air circuit for channeling air to and from the working chamber of the pump. The air circuit contains a solenoid operated air valve for restriction of outlet air, and sound insulation means for external sound reduction. The central mounting plate, impeller, impeller housing, and silencer housing are constructed of a polymeric material which allows complex features to be molded into the part thereby minimizing machining and assembly complexity.

Direct drive gas compressor

A reciprocating piston gas compressor 24 is driven by an integral internal combustion engine 22. The compressor may be used as an air compressor but has particular application for compressing natural gas from natural gas wells. It has few moving parts. The compressor has a reciprocating assembly 26, 35, 32, one end of which functions as the piston 26 in an engine and the other end of which functions as the piston 32 in a compressor. Motion of the assembly is regulated by a crankshaft 50. The crankshaft is connected to the reciprocating assembly pin-and-slot mechanism or by a linkage (Fig. 5) having arms (200) which pass on either side of the assembly. A vented distance piece prevents corrosive gases being compressed from entering the engine portion. Several compressors may be combined to make a multi-stage compressor.

Actuating the pump 40 directly by the crankshaft pump portion eliminates the typical drive train so as to reduce weight of the pump and engine combination while enhancing the reliability thereof and improving pump efficiency.

Вспомогательный привод двигателя внутреннего сгорания для воздушного компрессора

A gear wheel driven air compressor that is constructed as a piston compressor, the drive gear wheel of which, on the air compressor crankshaft, meshes with a gear wheel on the camshaft of the internal combustion engine. With drives of this type, the negative torque of the air compressor, which is produced once the upper dead center position of the air compressor piston has been reached, leads to a sudden flank change in the tooth mesh, which is associated with an unpleasant noise. In order to reduce this noise, it is known to make the meshing flank clearance as small as possible. However, clearances which are too small lead to increased rotational bending strain on the air compressor crankshaft and the camshaft. In order to prevent this, a sinusoidal meshing flank clearance change is proposed, which is obtained via a specific eccentricity of the air compressor drive gear wheel, which is associated with the upper dead center position of the air compressor piston.

Internal combustion engine combination with direct camshaft driven coolant pump

A coolant pump (26) is utilized with an internal combustion engine (10). The coolant pump has a pump housing (34), an impeller shaft (62), a pump impelle r (66), and a damper assembly (68). The housing (34) is fixedly mounted relati ve to the engine (10). The impeller shaft (62) is mounted directly to the camshaft (18) of the engine so as to be concentrically rotatably driven thereby. The impeller shaft (62) extends into the housing (34) in an unsupported relation, thereby eliminating the use of bearing in the coolant pump. The damper assembly (68) is disposed within the pump housing (34) and is rotatable to dampen torsional vibrations of the camshaft (18).

Internal combustion engine combination with direct camshaft driven coolant pump

A coolant pump for use with an internal combustion engine having a crankshaft and a camshaft driven by the crankshaft includes a pump housing fixedly mountable to the engine. The pump housing includes an inlet opening to receive coolant and an outlet opening to discharge coolant. An impeller shaft is operatively coupled to the camshaft so as to be rotatably driven thereby. A pump impeller is operatively mounted to the impeller shaft within the pump housing, the pump impeller rotatable to draw the coolant into the pump housing through the inlet opening and discharge the coolant at a higher pressure through the outlet opening. The pump impeller includes first and second shrouds separated by a plurality of vanes. The first and second shrouds and plurality of vanes are configured and positioned such that a resultant thrust load acting on the pump impeller and hence the impeller shaft is approximately zero.

Diesel Engine Pump for Fire Fighting

The present invention relates to a diesel engine pump for firefighting, comprising a governor (2) mounted on a diesel engine (1) to drive an engine pump (100) that supplies water to firefighting equipment such as sprinklers installed in buildings, etc. The diesel engine pump for firefighting further comprises a reducer (3) connected to a free end of a lever (21) mounted on the governor to control a speed of the diesel engine to a low speed for testing with the governor (2). The reducer (3) includes: a screw (31) having one end connected to the free end of the lever (21); a first gear (32) through which the screw (31) passes and is screwed to move left and right during rotation; a second gear (33) geared to an outer peripheral surface of the first gear (32); a reduction gear motor (34) rotating the second gear by mounting the second gear on an output shaft; and a timer (35) controlling the reduction gear motor (34) to operate at a preset speed and for a preset time in a preset cycle. In accordance with the present invention, in preparation for when the diesel engine cannot start due to an abnormality in an automatic control circuit, an emergency operation lever mounted on the governor can be operated manually to quickly extinguish a fire and protect life and property. In addition, when existing firefighting equipment in a building is checked, it is possible to prevent issues such as water spouting from sprinklers and the generation of noise and vibration.

Simple fire truck to move easily

본 발명은 이동이 용이한 간이 소방차에 관한 것으로서 보다 상세하게는 엔진에 의해 구동되는 펌프와는 별도로 모터를 이용하여 구동되는 이송바퀴에 의해 차량 진입이 어렵고 협소한 화재발생 지점까지 이동이 용이하고, 펌프 내부에 형성된 챔버와 흡입부 사이에 글루브를 형성시켜 밀봉수단에 전달되는 압력을 감압하도록 하여 밀봉수단의 파손을 방지하고, 초기 가동시 펌프흡입부에 설치된 윤활수흡입수단에 의하여 윤활작용과 냉각작용을 통하여 용적펌프의 내구성을 향상시킬 수 있도록 하는데 그 특징이 있다. The present invention relates to a simple fire truck that is easy to move, and more particularly, it is difficult to enter a vehicle by a transfer wheel driven by a motor separately from a pump driven by an engine, and is easy to move to a narrow fire occurrence point. A groove is formed between the chamber formed in the pump and the suction part to reduce the pressure transmitted to the sealing means to prevent breakage of the sealing means, and during initial operation, lubrication and cooling by the lubricating water suction means installed in the pump suction part. Through this function, it is possible to improve the durability of the volumetric pump.
