    Abstract: A flow adjustment device (1), comprising a distribution valve (2), which comprises a valve body (3) provided with a seat (4), which movably accommodates flow control means (5), with an intake port (6), which can be associated with means (A) for supplying a working fluid, with at least one discharge port (7; 7a; 7b), which can be associated with means (5) for discharging the working fluid and with a service port (8), which can be associated with a user device (U) with a fluid medium, the ports (7; 7a; 7b) being connected to the seat (4), and actuation means (9) for actuating the movement of the flow control means (5) within the seat (4), the flow control means (5) being adapted to assume alternately at least one first working position, in which they allow the connection of the intake port (6) and the service port (8), and a second working position, in which they allow the connection of the service port (8) and of the at least one discharge port (7; 7a), so as to obtain direct connection to the discharge means (5). The distribution valve (2) is of the type with three working positions, a third working position being also provided in which the flow control means (5) allow the connection of the service port (8) to the at least one discharge port (7; 7b) so as to obtain connection to the discharge means (S) by passing through a pressure adjustment valve (10), which is associated with the distribution valve (2) upstream or downstream of the at least one discharge port (7; 7b).

    Abstract: An apparatus incrementally reduces pressure in a first volume in response to an increase in pressure in a second volume. A valve body (110) defines a bore (111) that houses a piston (112) and supply and return passages (104,106) that communicate with first and second ends of the bore, respectively. The valve body also defines a release passage (170) that connects the bore with the first volume and an exhaust passage (180) that connects the bore with atmosphere. An inlet valve (140) opens when pressure in the second volume increases relative to pressure in the supply passage. An outlet valve (160) opens when pressure in the second volume decreases relative to pressure in the return passage. The piston is biased in a closed position against the first end and defines a passageway (120) through which the first and the second ends communicate. When pressure increases in the second volume, the inlet valve opens causing the first end (114) to pressurize and move the piston to an open position in which the release and exhaust passages communicate. This allows the first volume to vent gradually to atmosphere. As the pressure gradually equalizes between the first (114) and second (116) ends via the passageway, the piston returns to its closed position thereby discontinuing communication between the release and exhaust passages so that the first volume is cut off from atmosphere. When pressure decreases in the second volume, the outlet valve opens causing pressure to equalize between the supply and return passages via the passageway and to approximate the pressure in the second volume.

    Abstract: A caliper brake device includes a brake shoe for exerting a friction force by sliding in contact with a disk, a caliper main body fixed to a vehicle and an actuator for pressing the brake shoe against the disk. The actuator includes an elastic film that is fixed to the caliper main body, a drive pressure chamber that is defined by the elastic film and to which a fluid is supplied, a valve that introduces the fluid to the drive pressure chamber, and a piston that is interposed between the elastic film and the brake shoe. The fluid is supplied to the drive pressure chamber and the elastic film swells toward the brake shoe, whereby the piston brings the brake shoe into sliding contact with the disk. The valve introduces the fluid to the drive pressure chamber when the brake is applied while limiting the discharge of the fluid from the drive pressure chamber when the brake is released.
