Abrégé

A hydraulic valve for use with a lockable cam phaser. The hydraulic valve is configured to limit the flow of pressure medium to both the advance and retard chambers, while allowing a locking pin of the cam phaser to drain. The hydraulic valve effectively limits flow during the self-centering operation of the cam phaser. This is important for the system function, since it allows the phaser to select a side (i.e., the advance or retard chamber) to bleed off, reducing pressure on that side, which allows the cam phaser to move towards the mid-park (i.e., locking) position.

Abrégé

The invention relates to an oscillating motor camshaft adjuster (14) with an electromagnetically actuated hydraulic valve (12) that has a hollow piston (19) inserted into a bore (85) and longitudinally displaceable by means of an electromagnet (100), which hollow piston (19) is intended for distributing hydraulic fluid to two pressure chambers (9, 10) of the working connections (A, B) assigned to the oscillating motor camshaft adjuster (14). The first working connection (A) branches off from the bore (85) directly adjacent to the electromagnet (100). The hollow piston (19) has a circumferential stay with a control edge (107) facing the electromagnet (100). Thus a space (103) inside the bore (85) is bordered by the stay (102) and the electromagnet (100). A run-off opening (104) is provided in the hollow channel (19) between the stay (102) and the electromagnet (100). This run-off opening (104) hydraulically connects the space (103) to a run-off channel (105) leading to a tank drain (T) inside the hollow piston (19). The stay (102) can be displaced in a direction extending the first working connection (A) in the flow cross-section (106) by means of a force (F-M) of the electromagnet (100) supplied with current. This force (F-M) is directed counter to an elastic force (F-F) that presses the stay (102) in the direction reducing the flow cross-section (106). A throttle point (108) is provided at the stay (102), which throttle point (108) is arranged between the flow cross-section (106) and the space (103). Thus a high control quality is achieved.

Abrégé

The invention relates to an oscillating motor adjuster (14) with a hydraulic valve (12). Said hydraulic valve has a stepped bore (28) with working connections (A, B) outgoing therefrom. A pressure-equalised hollow piston (32) is axially movable within the bore (28). With a first outer diameter (D3), said hollow piston can be moved within a bore section (71) so as to have a toleranced sealing ability. Following this first outer diameter, the hollow piston (32) has - an adjacent lateral surface (47) with a large outer diameter (67) in the axial regions of the one working connection (A) and - a lateral surface (48) with a small outer diameter (D1) in the region of the other working connection (B). A leading edge (41 or 44) and a trailing edge (42 or 43) exit each of the two lateral surfaces (47, 48). The two leading edges (41, 44) face away from each other. The trailing edges (42, 43) face towards each other, and therefore a supply pressure admitted into a hollow space (80) of the hollow piston (32) is present on one side on a projected circular surface (60). Said circular surface (60) is formed from the small outer diameter (D1), and therefore a force (F1) is effective in an axial direction. In contrast, the supply pressure on the other side is present on a projected ring surface (61). Said ring surface is formed from the large outer diameter (67) minus the first outer diameter (D3). The hollow piston (32) is pressure-equalised due to the circular surface (60) being equal to the ring surface (61).

Abrégé

The invention relates to a hydraulic transmission valve with a magnetizable housing which is integrally configured in one piece with a pole core cone. The transmission valve according to the invention facilitates comfortably coupling in particular startup clutches, shifting clutches or synchronization clutches in a friction locking manner. Still using a transmission valve of this type is facilitated for fewer to no transmission oil changes. Furthermore a transmission valve of this type can also be used in countries with inferior transmission oil quality. The housing includes a connection. The connection defines an anchor stroke and a concentric arrangement between the pole core cone and a pole tube. Thus, the pole tube is fixated the magnetizable pole flange. An anchor that is exclusively supported in the pole tube is magnetically separated from the pole tube through a separation layer with a thickness of 0.01 mm to 0.06 mm.

Abrégé

A valve timing control apparatus (10) for a combustion engine is proposed, comprising a rotational member, preferably a sprocket (50), being driven by said combustion engine, a rotor (40) being mechanically coupled with a camshaft (42) for controlling opening and closing of cylinder valves of said combustion engine, a first configuration in which the rotor (40) is locked to the rotational member; and a second configuration in which the rotor (40) is unlocked from said rotational member, such that a switching phase of the valves in relation to said engine's rotational state can be controlled by an adjustable position between said rotational member and said rotor (40). In another aspect of the invention an operating method of said valve timing control apparatus (10) for adjusting a valve timing of a combustion engine is proposed. The variable valve timing control apparatus controls a relative rotation between a camshaft and an output shaft, which can either be prevented or permitted. A rotor being connected to said camshaft is releasably locked to a sprocket connected to said output shaft to thereby prevent relative rotation between the camshaft and the output shaft by a locking pin. The locking pin is driven by a hydraulic system which controls said cam phasing adjustment.

Abrégé

The invention relates to an oscillating-motor camshaft adjuster having a hydraulic valve, which has two working ports. These two working ports each have a standard opening axially adjacent to one another and an opening for the utilization of pressure peaks as a consequence of camshaft alternating torques. A hydraulic pressure can be guided from a supply port to the working port to be loaded, while the working port to be relieved of pressure is guided to a tank port. In order to also keep the control performance high in the case of internal combustion engines with very greatly fluctuating camshaft alternating torques, it is proposed according to the invention that a position of hydraulic valve can be controlled proportionally, in which the pressure peaks of the working port to be relieved of pressure are blocked relative to the supply port and the working port that is to be loaded.
