Description of drawings

Other advantage, feature and details of the present invention draws from following specification, has been described in detail with reference to the attached drawings different embodiments in specification.Accompanying drawing illustrates:

Fig. 1 passes receiving chamber according to the longitudinal section of the matrix of first embodiment's fluid technique controlling component;

Fig. 2 according to second embodiment, with Fig. 1 in similar matrix;

Fig. 3 is according to the plan view of the matrix of the 3rd embodiment's fluid technique controlling component;

The view of the section of the line IV-IV of Fig. 4 in Fig. 3, and

The side view that the matrix of Fig. 5 Fig. 3 is seen from the left side.

Embodiment

The matrix 1 of control block hydraulic unit with is shown with the longitudinal section of passing receiving chamber 4 in Fig. 1.These receiving chamber 4 usefulness are slightly represented on the surface of waveform, are used to show, cutting is no longer carried out on this surface.

In receiving chamber 4, receive reciprocating regulating element or control unit 18.This control unit 18 is spools 19, this spool have four with the synergistic flange 21 to 24 of (not illustrating) interface.Be configured for the guiding plug 26 of valve spring 28 in an end of spool 19.This valve spring 28 is used for spool 19 towards magnet 30 prestressing, and by this magnet, the precompression that spool 19 can overcome valve spring 28 moves in receiving chamber.

Valve plate 2 forms a vertical guiding valve with spool 19 and magnet 30, and this vertical guiding valve is also referred to as piston valve.This vertical guiding valve is the selector valve with distinct interface and switching position.

In Fig. 2 with the longitudinal section illustrate with Fig. 1 in similar matrix 41.This matrix 41 comprises the valve plate 42 with receiving chamber 44, and this receiving chamber is less times greater than the receiving chamber 4 of the valve plate shown in Fig. 12.This receiving chamber 44 illustrates with the surface of omiting undulate, is used to show that this surface no longer is cut processing.

Different with the embodiment of front, in receiving chamber 44, receive a sleeve 46.This sleeve 46 is gauge one doughnut in receiving chamber 44, and the sealed

element

47,48,49 of this doughnut is separated.Form interface area by these separating devices, the same function of connecting groove in the satisfied and traditional vertically guiding valve of these interface area.Receive one reciprocating, as to be spool 19 forms regulating element 18 in sleeve 46, the embodiment shown in the complete and Fig. 1 of this spool and spring 28 and magnet 30 constructs the samely.

Require low valve for valve is leaked, can move as spool or valve piston 19 directly not being had in the receiving chambers of making on cutting ground being seen at Fig. 1.The wave degree of receiving chamber 4 is illustrated large, to show the comparison between the boring of not having the receiving chamber 4 made on cutting ground and traditional cutting.For valve, must use as sleeve 46 shown in figure 2 with high requirement.

Important aspect according to the present invention,

valve plate

2,42 injection moulding of usefulness thermoset plastic material or compactings.In so-called spool box, exist bolt to connect in a plurality of positions.Port plate or valve plate and/or channel plate must connect with bolt mutually on the one hand.On the other hand other parts for example magnet must screw up.In order to realize that in thermoset plastic material these bolts connect, and exist different possibilities.

Can use known special bolt for thermosetting plastics on the one hand.Alternatively, can insert threaded insert at the transfer mold that is used for making plate.Alternatively, this threaded insert can be presented in the receiving hole that does not have cutting afterwards.

Another plate is formed from aluminium if having only a plate to make with thermoset plastic material, connects for the mutual bolt between the plate should be noted that: the generation screw thread in the plate that is formed from aluminium.Can reduce by this way by bolt and connect the problem of bringing.If two plates are made of a kind of thermoset plastic material, then can date back to previously described bolt connectivity scenario.Another program draws by the back side that nut is presented to plate.The opening that is used for nut accordingly can so design, and making does not need to be relatively fixed when tighting a bolt.

In Fig. 3 to 5, the matrix 51 of control block hydraulic unit with according to another embodiment of the present invention is shown with different views.This embodiment relates to the final controlling element plate 52 of gear box actuator.In final controlling element plate 52, offer the receiving chamber 54 to 57 of four same configuration altogether.In each of receiving chamber 54 to 57, receive a reciprocating final controlling element 60.This final controlling element 60 is gear shift pistons 61, and this gear shift piston is by two sliding sleeves 63, but 64 are directed to to-and-fro motion in the receiving chamber 55 of correspondence.

Two receiving chambers in the final controlling element plate 52 be opening and can be by 66 sealings of public lid.Two receiving

chambers

56,57 can be by another lid 68 sealings in the same way.Be provided with a circular groove 69 on gear shift piston 61, this circular groove can pass by one and cover 66 notch 70 and touch from the outside.This notch 70 allows reverse shift fork to pass and touches circular groove 69.This reverse shift fork so is embedded under assembling condition in the circular groove 69, makes corresponding gear shift piston 61 to operate by (not illustrating) reverse

shift fork.Lid

66,68 is fixed on the final controlling element plate 52 by six screws 72 respectively.

According to a further aspect in the invention, final controlling element plate 52 but also cover 66,68 usefulness thermoset plastic material and constitute not only.This final controlling element plate 52 can be as at the same passage that is provided with 42 of the valve plate shown in Fig. 1 and 22, and these passages allow hydraulic mediums to pass.According to a further aspect in the invention, these passages are directly made when making corresponding components with thermoset plastic material.

According to another importance of the present invention, shown port plate or

valve plate

2,42, final controlling element plate 52 and

cover

66,68 and in case of necessity spool 19 and final controlling element 60 do not have the ground of moulding in other words, cutting ground structure.This means that plastic components is deviate from and needn't be reprocessed from mould after die casting and/or injection moulding.
