Embodiment Construction

[0024] figure 1 Shows a front perspective view of an injector 2 detecting means 9a assembly embodiment of the present invention. Figure 2A and 2b From two different angles shows a perspective view of an assembly comprising a functional element 9a of the injector detecting means 2.

[0025] Injector 2 comprises detecting means figure 1 , 2a And 2b, respectively, shown on the right of the pressure generation region 4 and a detection region 5 on the left side are shown.

[0026] Injector detecting means 2 has a support frame 3, the support frame supporting the fluid pump (high pressure pump) 6 is configured for driving the fluid pump 6 and the motor 8.

[0027] The swingable frame 22 through the two bearing housing 26 is thus supported on the support frame 3, so that it can pivot about a horizontal axis. This implementation is possible to swing the frame 22 about a horizontal axis from the horizontal to the vertical at an arbitrary angle adjustment. The swingable frame 22 is fixed b...

Abstract

The invention relates to an injector testing device (2) comprising: a fluid pump (6) designed to deliver test oil; a motor (4) mechanically connected to the fluid pump (6) and driven configured to drive the fluid pump (6); at least one injector holder (16) configured to accommodate at least one injector (18) to be tested; and a track (10) configured to accommodate The test oil delivered by the fluid pump (6) is used for fluid connection with at least one injector (18) to be tested. The rail (10) is arranged in the injector testing device (2) in such a way that it can be swiveled relative to the at least one injector carrier (16) in order to direct it towards the injector testing device (2). The injector (18) is directed.

Description

Technical field [0001] The present invention relates to an injector detecting means. Background technique [0002] To detect the injector in the injector detecting means, a high-pressure pump ( "pump Common Rail") will be raised to detect the oil pressure required, and the detected pressure oil is supplied to the memory or the high voltage rail. Detecting the oil pressure of the memory allocated to the high voltage rail or injector to be detected. [0003] The configuration of the type of injector to be detected, to be used in this connection various catheters, particularly high pressure hose to the injector connected to the pressure reservoir or the high voltage rail. [0004] A flexible conduit connected, in particular connected to the conduit from different manufacturers may affect the measurement result, thereby generating correlated with a single or a few manufacturers. Even if a single high pressure hose manufacturer, measurements may fluctuate because of manufacturing tole...
