A method and a system are provided for adjusting a pressure of a medium to a target pressure. The method includes: providing a pneumatic structure in which the medium is at a medium pressure that is a starting pressure; providing an adsorptive material operable within a range of temperatures that is proportionate with a range of medium pressures at which the pneumatic structure is operable; and adjusting a temperature of the adsorptive material to effect an adjustment of the medium pressure to the target pressure for performing a selected function. The system performs the method and includes the absorptive material and at least one regulator for adjusting the temperature of the adsorptive material.

An emergency braking device including an actuator (2), a pressurizing circuit (3) supplying the actuator (2) via a control pressure and a discharge circuit (4). The discharge circuit (4) includes restrictors (13, 14) for controlling the pressure and/or flow rate of the supply fluid of the actuator (2) during a discharge of the actuator. The restrictors (13, 14) are configured to define an intermediate pressure between a low pressure level and the control pressure of the actuator (2).

An on-board pressurized washing system that utilizes a semi-tractor or trailer's compressed air brake line as its source of compressed air. When the tractor is parked, the air brake lines may be disconnected from the trailer and hooked up to the pressurized washing system. The system is fully mobile and does not need an external power source or water line during operation. The water from the water tank and the compressed air are sprayed separately or together from a spray wand to meet cleaning and sanitation needs of truck drivers in any location when they may not have access to electricity or a water source.

A pump attenuator bypass valve (40/100/200) is located at an outlet of a pump (30) in a vehicle braking system (10) between the pump (30) and an attenuator (34). The attenuator bypass valve (40/100/200) includes a bypass valve housing (41), a first fluid flow path (74, 57/179/220, 208), and a second fluid flow path (80/183). The first fluid flow path (74, 57/179/220, 208) is defined in the housing (41) and is configured to allow continuous flow of fluid when the pump (30) operates at a first pump flow rate. The second fluid flow path (80/183) is defined in the housing (41) and is configured to bypass the first fluid flow path (74, 57/179/220, 208) and to allow continuous flow of fluid when the pump (30) operates at a second pump flow rate higher than the first pump flow rate.
