The disclosure relates to a pressure distributor for a motor vehicle, in particular for pneumatic actuators in seats, wherein a pressure generator and a plurality of pneumatic actuators can be connected to the pressure distributor, wherein each actuator is assigned at least one electrically controllable valve which forwards a pressure which is generated by the pressure generator in a targeted manner via a respective outlet to the actuator which is assigned to it, wherein the plurality of valves are supplied with compressed air by the pressure generator during operation of the pressure distributor via a respective inlet of a common air inlet line. The common air inlet line is connected as a separate component via a releasable connection to the plurality of valves.

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.

Provided is an electric work vehicle having a simple configuration, yet allowing a hydraulic cylinder to function appropriately even in a low-temperature environment. An electric work vehicle includes a first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder and includes also a hydraulic system for feeding work oil to these hydraulic cylinders and a traveling motor. The hydraulic system includes an oil heating circuit for heating the work oil using heat generated from the traveling motor.

An electropneumatic control apparatus, which has a carrier module, on which a control unit, which is equipped with control electronics and control valve elements, and an expansion module assembly, which has at least one expansion module, are installed independently of each other. By means of a drive fastening interface, the control apparatus can be installed on the actuating drive to be controlled, in order to form a process control device.

A Hydraulic Manifold Control Assembly for use in connection with surface blowout preventers and diverter control systems. Said Hydraulic Manifold Control Assembly incorporates design elements and methods which reduce overall envelope dimensions, improving maintenance accessibility, thereby reducing overall installation and manufacturing time and ultimately contributing to a more robust, cost effective end-product. Said design elements and methods include: the use of intrinsically safe I/O modules and components; the employment of a removable valve assembly rack installation method; the use of a removable face plate for identification of flow control valves; the implementation of a digital automatic diverter sequence; the use of integrated manifold assemblies; and the integration of a wide-range function count.

An engine-driven oil pump has an engine, a pump unit, an oil diverting device, a manual control unit, and a remote control unit. The engine is connected to the pump unit. The oil diverting device is mounted on the pump unit and selectively pumps hydraulic oil from the pump unit into the manual control unit or the remote control unit. With the engine, the engine-driven oil pump can generate power independently instead of relying on external power supply. Besides, the electromagnetic valve of the remote control unit allows the user to remotely control the oil path of the hydraulic oil, so the user is not required to stay along the engine-driven oil pump to manually switch the oil path, and therefore the engine-driven oil pump is more efficient regarding manpower.

An actuator is usable in an airside system, waterside system, building management system, or HVAC system. The actuator includes a housing. The housing has a socket with an interior passage that includes a male connector. The socket may extend outwardly from the housing. The actuator also includes an overmolded cable sized to fit in the interior passage and including a female connector that receives the male connector within the socket. The actuator includes a coupling device that surrounds the overmolded cable and is coupled to the socket and maintains an electrical connection between the male connector and female connector.

A hydraulic system (1) is provided comprising a group of at least two valves (2a, 2b, 2c) connected to a bus (8), each of said valves (2a, 2b, 2c) comprising a primary memory (9a, 9b, 9c) for storing a set of parameters of the valve (2a, 2b, 2c). The service work of such a hydraulic system should be facilitated. To this end each valve (2a, 2b, 2c) comprises a secondary memory (10a, 10b, 10c) storing said set of parameters of a different valve (2b, 2c, 2a) of said group.

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.
