摘要： PROBLEM TO BE SOLVED: To reduce a heat quantity from an engine to a high pressure pump, namely, into a fuel circulating passage, and prevent a rise in temperature of fuel by maximizing the number and a surface of an air gap between the high pressure pump and a part of an internal combustion engine. SOLUTION: A high pressure pump 1 in a common rail type injection system for feeding fuel of a diesel engine is fastened and fixed to an internal combustion engine in a flange 2 disposed on the high pressure pump 1. In this case, a plurality of cutouts 6 are formed on the flange 2 in regions of bolt passing holes 3 to 5. Accordingly, a contact surface of a joining part of the high pressure pump 1 and the internal combustion engine is contracted. A centering web 7 useful for obtaining correct centering at the time of assembling of the high pressure pump 1 is formed in the flange 2, and an annular (a ring shaped) abutting surface 9 is concentrically arranged. The annular abutting surface 9 is formed by recessing to the high pressure pump 1 side so as to prevent from abutting on the internal combustion engine.

摘要： PROBLEM TO BE SOLVED: To partially charge a cylinder chamber of a radial piston pump. SOLUTION: A driving shaft 4 borne in a pump casing has a deflectively constituted shaft division 6. One ring 8 is slidably borne on this shaft division 6. This ring 8 cooperates with a piston 12 arranged in each cylinder chamber 19 radially in relation to the driving shaft 4. Each end on the driving shaft 4 side of the piston 12 has one plate 14. All plates 14 are kept in a contact condition with the ring 8 by a plate spring shaped device 16.

摘要： PROBLEM TO BE SOLVED: To simply superintend a pressure limiting valve at low costs by controlling a pressure control means in a fixed operating condition, connecting the high pressure territory to the low pressure territory through the pressure limiting valve in the non-error condition, and evaluating the pressure of the high pressure territory for discriminating an error. SOLUTION: The discharge side of a discharge pump 110 connected to a fuel tank 100 is connected to a fuel rail 130 connected with injectors 131,... through a valve 120, a high pressure pump 125, and the like. Further a pressure regulator valve 135 and a pressure limiting valve 145 are interposed on a pair of parallel pipe lines discharging surplus fuel from the fuel rail 130 to the tank 100, and the pressure of a high pressure territory between the high pressure pump 125 and the pressure regulator valve 135 is detected by a sensor 150. When the internal combustion engine is changed to be cut off, the pressure is raised till response of the pressure limiting valve 145, and when the pressure of the pressure limiting valve 145 exceeds a fixed value at pressure drop thereafter, it is judged to generate obstruction, and shifted to a emergent running mode.

摘要： A radial piston pump for high-pressure fuel supply in fuel injection systems of internal combustion engines, in particular in a common rail injection system, has an input shaft (4) mounted in a pump housing (2), and preferably several pistons (10) which are radially arranged with respect to the input shaft (4), each in its cylinder chamber (12), and which can move back and forth in the radial direction. A metallic insert (22) which forms the cylinder chamber (12) is provided for each piston (10) within the housing (2) and oriented radially with respect to the input shaft (4). The insert (22) communicates with the suction side (40) and with the high-pressure side (42). In order to define the component parts in a statically exact manner, the pump is designed such that each insert (22) is arranged between two flange-shaped metallic housing parts (48, 50) with supporting surfaces (24, 24; 52, 54) perpendicular to the input shaft and is supported on said surfaces. Each insert (22) has a fuel inlet (32) and a fuel outlet (34) which open in the region of the supporting surfaces (24, 26) and are aligned with another inlet and outlet (58, 60) in the housing parts (48, 50). The flange-shaped housing parts (48, 50) are clamped together, with the intercalated inserts (22), so that the supporting surfaces (24, 26; 52, 54) of the inserts (22) and housing parts (48, 50) are sealed in a high-pressure-tight manner without any intercalated packing elements.

摘要： High-pressure piston pump (6) with several pump elements (7) that is connected to a low-pressure flow-regulated pump (1) on the suction side. A first and a second check valve (10, 11) are connected in series to each pump element (7) on the suction side. The first check valve (10) opens against the force of a spring during the suction phase of the pump element (7) and closes during the delivery phase. The second check valve (11) opens against the force of a spring and closes assisted by the force of a spring when the fuel delivered by the pump (1) reaches pressures that are higher than the negative pressure generated in a cylinder chamber (9) of the pump element (7). The second check valve (11) regulates the amount of fuel delivered to the pump element (7). The first check valve (10) blocks the cylinder chamber (9) from the check valve (11) during the delivery phase. The piston pump ensures generation of high pressure fuel in fuel injection systems in internal combustion engines, especially in a common rail injection system.
