A fluid pressure control device includes a first circuit system having a first pump and a first control valve. The first circuit system includes an intermediate cut valve provided downstream of the first control valve in a first intermediate passage and which connects and disconnects a connection between the first intermediate passage and the tank, and an external output port communicating at a part downstream of the first control valve in the first intermediate passage and upstream of the intermediate cut valve, the external output port being capable of externally supplying working fluid discharged from the first pump.

A fluid control device includes a housing and a fluid temperature control assembly. The housing includes a first inlet, a second inlet for receiving a fluid, and a first outlet through which a fluid of a third temperature flows. The fluid temperature control assembly is in the housing, with apertures for regulating fluid communication between a mixing cavity and the first inlet of the housing, apertures communicating with the first outlet. The fluid temperature control assembly modifies properties of the apertures for regulating the amount of fluid having a first temperature relative to the amount of fluid having a second temperature with the mixing cavity, thereby maintaining the fluid discharged from the first outlet at a predetermined temperature.

A gas delivery system for a substrate processing system includes first and second valves, a first gas channel, and a cylinder. The first valve includes a first inlet and a first outlet. The first outlet is in fluid communication with a processing chamber of the substrate processing system. The second valve includes a second inlet and a second outlet. The cylinder defines a second gas channel having a first end and a second end. The cylinder is at least partially disposed within the first gas channel such that the cylinder and the first gas channel collectively define a flow channel. The flow channel is in fluid communication with the first end of the second gas channel and with the first inlet. A third gas channel is in fluid communication with the second end of the second gas channel and with the second inlet.

A tool cabinet having integral pneumatic air lines. The present invention is a tool cabinet having an inlet valve, which is adapted to have an air compressor attached thereto, and a plurality of outlet valves, which are adapted to have a variety of different pneumatic tools connected thereto. The present invention also has a plurality of holders disposed on the exterior surface of the tool cabinet to hold the pneumatic tools. The present invention is otherwise designed to function as a traditional tool cabinet, including having a plurality of drawers, hooks, slots, or other such structures adapted to hold and organize tools.

A fluid control device 10 comprises a valve device V2 including actuators 22 and 24 for opening and closing a flow path and adjusting a flow rate of a fluid flowing through the flow path, a pressure sensor PT provided upstream of the valve device V2, and a control circuit 12 connected to the valve device V2 and the pressure sensor PT, and the control circuit 12 controls an operation of the actuator based on a pressure measured by the pressure sensor PT and a reference pressure drop curve, while the upstream side of the fluid control device is closed and the valve device is opened using the actuators.

An electric valve device including a hollow body with an inlet and an outlet for a flow of fluid, in particular a liquid, between which, inside said body, there is defined a chamber in which there is provided a valve seat intended to cooperate with an associated closing member for controlling communication between the inlet and the outlet; and a tubular guiding formation which is nominally coaxial with the valve seat and inside which there is mounted, axially displaceably to and from the seat, a core which carries the closing member and the position of which with respect to the seat can be electromagnetically controlled by means of a winding or solenoid arranged around said tubular formation. The hollow body and the tubular guiding formation are made as a single piece of moulded plastic.

A hydraulic block for a hydraulic unit is configured to control the brake pressure in a slip-controlled vehicle brake system. Multiple pressure sensors are received in receptors that are defined by the hydraulic block and that are configured to place each of the pressure sensors in hydraulic contact with a respective brake circuit. The pressure sensors are configured to detect wheel brake pressures in the corresponding brake circuits. The hydraulic contact between the pressure sensors and the brake circuits is enabled by a common duct that includes a shut-off element configured to block a pressure medium connection between the brake circuits.

The present invention relates to a multiple coupling manifold comprising a plurality of housings configured to accommodate an equal number of hydraulic couplings.

The manifold according to the invention is characterized in that it comprises first and second hydraulic connection means configured to hydraulically connect said manifold to the hydraulic circuit present on the machine once the manifold is mounted on the machine, and is further characterized in that it comprises a first hydraulic connection pipe, which connects said first hydraulic connection means to a first and a second of said housings, and a second hydraulic connection pipe, which connects said second hydraulic connection means to a third and a fourth of said housings.

A noise-reducing valve structure includes a unitary spindle-shaped body having a central lumen for receiving a fluid flow and a poppet member, the body having an inner diameter adjacent the central lumen and an outer diameter and a circumferentially and axially distributed plurality of radial passages adapted to be opened and closed in accordance with a guided position of the poppet member, the plurality of radial passages extending through the spindle-shaped body from the inner diameter to the outer diameter and having a gradually increasing area from the inner diameter to the outer diameter.

An electronic device for controlling pressure regulators, enabling remote adjustments and corrections for pressure drops and supply line expansion is provided.
