Definitions
- FIG. 1 the coolant valve in longitudinal section
- a closing piston 15 arranged coaxially with the tappet 12 and with the control piston 13 moves in the pressure chamber 7, the axial end faces 16 and 17 of which on the one hand have a back pressure chamber 18 in which the control bore 9 opens, and on the other hand one Limit the flow space 19 in which the inlet 2 opens.
- the closing piston 15 is guided in the pressure chamber 7 via a sealing gap between the outer circumferential surface 20 of the closing piston 15 and the inner circumferential surface 21 of the pressure chamber 7.
- a pressure channel 22 penetrating the closing piston 15 connects the dynamic pressure chamber 18 permanently with the inlet 2, whose opening in the flow chamber 19 is limited by a valve seat 23.
- the cross-sectional area delimited by the valve seat 23 is smaller than the cross-sectional area of the pressure chamber 7.
- FIGS. 2a to 2d show the section in the area of the control bore 9 that is relevant for the pilot control of the coolant valve 1. Reference numbers not drawn in there are shown in FIG.
- FIG. 2a The coolant valve 1 is completely open for maximum flow between the inlet 2 and the outlet 4.
- the control piston 13 When the actuator 11 is switched off, the control piston 13 is in the retracted position, in which the pressure-relieving connection between the pressure relief chamber 8 and the dynamic pressure chamber 18 is established via the control bore 9.
- the end face 16 of the closing piston 15 delimiting the dynamic pressure space 18 is spaced from the actuating end face 25 of the control piston 13 and rests with the guided outer diameter area on the partition 26 between the dynamic pressure space 18 and the pressure relief space 8.
- control bore 9 is just closed by the control piston 13, while the position of the closing piston 15 adjacent to the partition 26 is unchanged compared to Figure 2a.
- This special case can be modified by an earlier or later contact with the closing piston 15 in relation to the closing of the control bore 9 who the.
- the control bore 9 is closed by the outer circumferential surface 27 of the control piston 13, which forms a sealing gap with the inner circumferential surface 28 of the control bore 9 (see FIG. 2c).
- the guidance of the control piston 13 in the control bore 9 can, if necessary, be improved by guide ribs, not shown, which run axially on the side of the closing piston 15 next to the sealing outer jacket surface 27 on the control piston 13.
