Problems solved by technology

[0008] However, in the valve device of JP2006-300197A, although the removal (disengagement) of the valve seat member can be restricted, the valve seat member can move in a direction parallel to the plane of the valve seat member in the receiving area, and thus the valve seat The position of the component is unstable
Furthermore, when the position of the spring is shifted in response to movement of the seat member, the output characteristics of the valve device may change and / or wear of the wall surface of the valve element's spring-receiving area may occur due to buckling of the spring

Embodiment Construction

[0022] Hereinafter, embodiments of the present disclosure will be described. Here, it should be noted that the following embodiments disclose specific examples, but the present disclosure is not necessarily limited to the following embodiments.

[0023] (Structure of the embodiment)

[0024] will refer to Figure 1 to Figure 4 The structure of the valve device 1 of the present embodiment is described.

[0025] The valve device 1 comprises a body 3 forming an oil pressure circuit 2 configured to supply oil pressure to each corresponding friction element of a plurality of friction elements of a transmission of a vehicle, eg a motor vehicle. The valve device 1 forms a part of a driving force transmission device that transmits a driving force generated from an internal combustion engine to driving wheels of a vehicle. The valve device 1 is used in the oil pressure circuit 2 to change the oil circuit and / or adjust the oil pressure.

[0026] Hereinafter, the valve device 1 will ...

Abstract

The present invention relates to valve arrangements. In the valve seat member (5) received in the receiving area (012) of the first body (3A) of the body (3), one surface of the contact portion (5A) and one surface of the engagement portion (5B) are planar and flush with each other, the other surface of the contact portion (5A) and the other surface of the engagement portion (5B) are planar and flush with each other. The engagement portion (5B) engages the first body (3A) to form one opening (12a) of the receiving area (12) in a state where the distal end of the valve seat member (5) reaches the other opening (12b) of the receiving area (12). Two parts (12aa, 12ab). Furthermore, the second body (3B) of the body (3) covers one opening (12a) and contacts the engagement portion (5B) in a state where the engagement portion (5B) engages the first body (3A) portion ( 12aa, 12ab ). Thus, the engagement portion (5B) engages the three parts (12aa, 12ab, 3Ba) of the body (3) such that the movement of the valve seat member (5) is effectively restricted.

Description

technical field [0001] The invention relates to a valve device comprising a body forming an oil pressure circuit configured to supply oil pressure to friction elements of a transmission of a vehicle. Background technique [0002] Previously, a valve device was known comprising a body, a valve element in the form of a slide valve, and a valve seat part in the form of a plate (see eg JP4460107B2). [0003] refer to Figure 5 and Figure 6 , the disadvantages of previously proposed valve arrangements of the above type will be described. Such as Figure 5 and Figure 6 As shown, in the previously proposed valve device 100, the body 101 forms an oil pressure circuit supplying oil pressure to each corresponding friction element in a plurality of friction elements of the transmission of the vehicle, and the valve element 102 is such that the valve element 102 The valve element 102 is received in the hole 103 of the body 101 so as to be movable in the axial direction of the valve...
