A method of manufacturing a hydraulic valve component using additive manufacturing includes laying successive layers to form a flow aperture for a hydraulic valve component, and creating a lattice or mesh structure that at least partially defines the flow aperture of the hydraulic valve component, or a feature that forms an undercut along a direction that is parallel to a flow direction of the flow aperture, or a flow aperture having a size varying along a circumferential direction of the valve component.

A hydraulic block of an electronic braking device for a vehicle may include: a block body including a controller mounting part to which an electronic control unit (ECU) is coupled and a motor mounting part to which a motor is coupled; an input port part disposed closer to the controller mounting part between the controller mounting part and the motor mounting part; an output port part disposed closer to the motor mounting part between the controller mounting part and the motor mounting part; and a hydraulic circuit part formed in the block body so as to extend from the input port part to the output port part, and housing a valve controlled by the ECU.

A hydraulic block of an electronic braking device for a vehicle may include: a block body; an input port part disposed on the block body, and connected to an output line of a main braking device to brake a vehicle using hydraulic pressure; an output port part connected to a hydraulic brake line for individually adjusting one or more wheels; and a hydraulic circuit part formed in the block body so as to extend from the input port part to the output port part, and configured to control hydraulic pressure for redundancy of vehicle braking.

The flow rate control unit 1 is comprised with each of the flow rate control devices 11 connected to (juxtaposedly mounted on) the manifold 2 by the joint 91 interposed between each of the flow rate control devices 11 and the manifold 2. Each of the flow rate control devices 11 can be attached to or detached from the manifold 2 by manually operating (attaching/detaching) the clip 93 without using a tool. Because there is no need to secure space to insert a tool between the adjacent flow rate control devices 11, the mounting pitch between the adjacent flow rate control devices 11 (joints 91) can be reduced to the minimum, allowing miniaturization of the flow rate control unit 1.

The present invention relates to a fluid control device and a connector for the same. The connector includes a first unit and a second unit to form a connector in a particular shape. Thus, the connector and an adjacent connector can be stacked upon each other to allow simple disassembling. The present invention also provides a fluid control device including the connector.

A controller for a valve assembly that is configured to meet requirements for use in hazardous areas. These configurations may regulate flow of instrument air to a pneumatic actuator to operate a valve. The controller may comprise enclosures, including a first enclosure and a second enclosure, each having a peripheral wall forming an interior space, and circuitry comprising a barrier circuit disposed in the interior space of one of the enclosures that power limits digital signals that exits that enclosure. In one example, the peripheral wall of enclosures are configured to allow instrument air into the interior space of the first enclosure but to prevent instrument air from the interior space of the second enclosure.

A segmented fluid end assembly has a first module having a body with a first side surface and a slot formed therein and extending along at least a portion of the first side surface, a second module having a body with a first side surface and having a slot formed in the first side surface and generally aligned with the slot of the first module, and a connector received in the slots of the first and second module so as to fix the first module against the second module. The connector is in the nature of a wedge. Each of the slots has a generally dovetail configuration. The wedge has a generally hourglass cross-section. The wedge is engaged in friction-fit relationship in the slots.

A compressed air provision device (2) for aerating a first pressure chamber (10) of a pneumatic actuator in order to actuate an actuator element (11) of the pneumatic actuator (3) in accordance with an actuation specification, in particular a position, movement, pressure and/or force specification. The compressed air provision device (2) is configured to calculate an aeration period (bd) and to aerate the first pressure chamber (10) in accordance with the calculated aeration period (bd) in order to bring about actuation of the actuator element (11) in accordance with the actuation specification.

A control module for an air treatment system of a utility vehicle comprises the following: a first and second pneumatic magnetic valve having a first or second coil, connecting pins, and armatures accommodated in the coils, a circuit carrier, and a module housing that is cast from a plastic material, into which housing the coils are cast. The connecting pins project from a first side of the module housing and are electrically connected to the circuit carrier. A plug-in connection for receiving a connection plug is formed in the module housing, wherein the plug-in connection has plug-in pins, which extend through the module housing and are electrically connected to the circuit carrier. The module housing has a mounting surface having pneumatic connections for installation on an air dryer housing of an air dryer.
