摘要： The invention relates to a controllable coolant pump driven by a belt pulley for internal combustion engines. The aim of the invention is to develop a controllable coolant pump (having a gate valve) driven by a belt pulley, allowing significant reduction in both pollutant emissions and frictional losses and fuel consumption over the entire working range of the engine, and allowing reliable actuation of the gate valve with very low drive power, even under unfavorable thermal boundary conditions, such as in proximity of the turbocharger, as well as under very limited installation space, and ensuring continued functioning of the coolant pump (fail-safe) even if the controller fails, and characterized by a very simple, low-cost production and assembly design “standardized” for different pump sizes, thereby ensuring continuously high operational reliability at a high volumetric efficiency, and requiring no air-free charging in the factory, and that can be simply and inexpensively integrated in the engine management system. The controllable coolant pump according to the invention, having a gate valve and driven by a belt pulley (3) and having a hydraulically actuated gate valve connected to a ring piston (29) is characterized in that an axial piston pump (61) disposed in the pump housing (1) is driven and “operated” by means of a swashplate (32) having a suction groove (33) and disposed on the back side of the flywheel (5), the “pumped volume flow” thereof being controlled in a defined manner by means of a solenoid valve (13) such that precise displacement of the hydraulically actuated gate valve is ensured.

摘要： The invention relates to a switchable coolant pump for combustion engines which is driven by a pulley, wherein the impeller can be driven switchably by the pulley by way of a friction pairing. It is the aim of the invention to develop a switchable coolant pump for combustion engines of the above type, which is simple to manufacture in terms of the manufacturing engineering thereof, driven by a pulley, and which is suited particularly for smaller coolant pumps (which is to say, coolant pumps in which the distance between the pulley and the impeller is smaller than 15 mm and the pulley diameter of which is smaller than 50 mm). The switchable coolant pump according to the invention, comprising a connecting flange (9) for a pressure booster (10), the flange being disposed on the pump housing (1), and a working piston (14) disposed in a working cylinder (15), is characterized, among other things, in that on/in the pump housing (1) both the pulley (3) in a pulley bearing (2) and the pump shaft (5) in a pump bearing (4) are mounted separately, and a sleeve receptacle (17) is disposed in the pump housing (1), wherein an annular channel (19) is located in the annular bottom (18) of the receptacle, and an annular piston working sleeve (21) is inserted in the sleeve receptacle (17) in the pump housing (1), and an annular piston (24) that is provided with an annular piston packing (23) is disposed displaceably in the annular piston working sleeve (21). The pump is further characterized in that an axial bearing (25) is disposed adjacent to the annular piston (24) on the pulley side and between the annular piston (24) and a working cone (26), a final position delimitation (27) for the working cone (26) and one or more return springs (28) are disposed on the pump shaft (5), and centrally in the face (29) of the pulley (3) a driving cone (30) is disposed, which is operatively connected to the working cone (26) disposed on the pump shaft (5) when applying a negative pressure or positive pressure to the pressure connector (12).

摘要： A regulatable coolant pump and a method for regulation of this regulatable coolant pump for internal combustion engines, which is driven by way of a pulley actives a valve slide using an electromagnetically activated piston pump equipped with a return spring in the form of a pressure spring. The pump implements a “pump feed” using many small “partial lifts.” A “leakage volume stream” that flows opposite to the “pumped volume stream” is superimposed on the “pumped volume stream” via the arrangement of circular apertures both in the inlet valve membrane of the working piston and in the outlet valve membrane so that the valve slide can be moved in defined manner and in a very robust and reliable manner, with low drive power via the defined superimposition of these two volume streams.

摘要： An engine brake for a multicylinder internal combustion engine includes valves that can be periodically opened briefly, in each case outside the exhaust stroke. In the vicinity of the applicable valve drive, a hydraulic piston is provided that is triggered synchronously with the engine rpm via an associated control line by a hydraulic pressure distributor fed by a pump. To improve the accuracy of control over the entire engine rpm range, the various valves are assigned a central positive displacement pump that runs synchronously with the camshaft rpm and whose outlet line leads to the hydraulic pressure distributor, which has a distributor disk. In engine braking operation, an alternating connection of the applicable control line to either the pump outlet line or a low-pressure region of the hydraulic control circuit is effected synchronously with the engine rpm by means of the distributor disk.
