Embodiment
A kind of cylinder cap with the high-pressure fuel pump in multiple interconnective hole 1,4,5,10,11 as can be seen from Figure 1.First hole is configured for the pressure hole 1 of the pump piston (not shown) of the pump element receiving described high-pressure service pump.In hole 1 internal structure pump working chamber 2, fuel is compressed by the motion of described pump piston.Described fuel arrives in pump working chamber 2 by suction valve (not shown), in order to receive described suction valve, arranges the hole 4 coaxially arranged with pressure hole 1 in described cylinder cap.Described suction valve thus restrictive pump working room 2 or pressure hole 1 in the axial direction.After described compression, described fuel arrives with the high pressure valve (not shown) be arranged in here the high-pressure outlet that first is configured to convex shoulder 8 by the other hole 5 for pressure hole 1 radial arrangement.The described high-pressure outlet being configured to convex shoulder 8 has hole 10, hole 10 with coaxially arrange for the hole 5 receiving described high pressure valve, wherein, hole 10 has the diameter larger than the diameter in hole 5, for receiving pressure transducer 17.Thus hole 5,10 obtains the shoulder hole of a radial outward dilations.If pressure transducer 17 is arranged in hole 10, described cylinder cap also bears described pressure measurement except fuel compression function.
As shown in Figure 2, described cylinder cap also has second other, that be configured to convex shoulder 9 respectively, to have the hole 11 for described injector interface high-pressure outlet.This some holes also substantially about pressure hole 1 radial arrangement, thus obtains a kind of compact structure.By connecting passage 12, the hole 11 for described injector interface is connected with the hole 10 for receiving pressure transducer 17.Thus the pressure transducer 17 be received in hole 10 can carry out pressure measurement to the fuel pressure in described second high-pressure outlet.
The high-pressure outlet of convex shoulder 8,9 and the other injector interface 13 of arranging perpendicular to it is configured to from the plan view of Fig. 3 is known.Fig. 3 also shows that hole 14 also receives fixing bolt on the upside at described cylinder cap, and described cylinder cap utilizes described fixing bolt can be fixed on the housing of described high-pressure fuel pump.In addition the known described hole 4 with pressure hole 1 coaxial arrangement, described suction valve can be arranged in hole 4.
The cylinder cap of Figure 4 and 5 shows the remodeling of cylinder cap shown in Fig. 1 to 3.In this embodiment, such as arrange the high-pressure outlet that three are configured to convex shoulder 9 equally, described high-pressure outlet has hole 11 respectively, wherein, arranges a high pressure valve 7 (see Fig. 5) being configured to safety check in each hole 11.Thus each hole 11 is used as the hole 5 of a reception high pressure valve 7.Independent hole 5 can be omitted, and thus this mode of execution is especially compact structure.Even so, arrange a high pressure valve 7 in each hole 11, this is suitable.In addition, the high-pressure outlet being configured to convex shoulder 9 forms the slice location of described injector interface.Also learn an other hole 15 from Fig. 5, it is used as entrance (also see Fig. 4).
The hole 11 of convex shoulder 9 is radially arranged about the pressure hole 1 of described cylinder cap.This layout can use four high-pressure outlets at the most to form.Thus the high pressure valve 7 be arranged in hole 11 is limited in the pump working chamber 2 formed in pressure hole 1 in radial directions.Relatively, coaxially arrange with pressure hole 1 for the hole 4 receiving suction valve 6, hole 4 is restrictive pump working room 2 in the axial direction.Pump working chamber 2 is subject to another restriction (see Fig. 4) in the axial direction by the pump piston 3 that is received in pressure hole 1.
Also as seen from Figure 4 from the hole 16 of hole 11 or 5 branch for receiving high pressure valve 7, hole 16 is directed to for tonometric pressure transducer 17.Hole 16 can be configured to intercommunicating pore or be configured to receiving hole, and thus pressure transducer 17 is selectively integrated in described cylinder cap.Pressure transducer 17 layout be arranged in the region of high-pressure outlet is enough to carry out pressure measurement to described high-pressure area.
Because the diversity of structure, cylinder cap according to the present invention is applicable to a series of high-pressure service pump.Such as, but preferably, adopt the high-pressure fuel pump being configured to radial piston pump, it also has multiple, three pump elements, and wherein, each pump element is attached troops to a unit in corresponding cylinder cap.
