摘要:
A hydrostatic power steering system is provided of the type including a steering control unit (3) operated by an input such as a steering wheel (1) to control flow from a source (8) to a steering cylinder (7). The source is operated in response to an electrical signal from a controller (82), controlled by a sensed pressure at a pressure detection port (64). The pressure at the port (64) is communicated from the main fluid path of the steering control unit (3), downstream of the fluid meter (18) when the spool (21) and sleeve (22) are relatively displaced. In systems in which the system reservoir (R) is at an elevated ("regulated tank") pressure, the pressure detection circuit is drained through a variable orifice (70) to a drain port (66), which is in communication with a sump (S) maintained at substantially atmospheric pressure. As a result, the steering system responds at a lower steering pressure, and the initial steering is smoother.

A bottle shape is provided that allows for volume-reducing deformation of a peripheral wall of the body, while maintaining stable posture of the bottle by making use of a combination of a refill container and a regularly used container having an upright discharge cylinder segment. The body is formed to have a thin peripheral wall so that volume-reducing deformation would take place along with the depressurization going on inside the bottle. The peripheral wall has three ridge lines formed in a mountain fold at approximately equal intervals in the vertical direction and has three panel walls connected to one another. Each panel wall is bordered by two adjacent ridge lines, and has a valley fold line that diagonally connects an upper end of one ridge line to a lower end of another adjacent ridge line so that three valley fold lines are disposed obliquely in parallel along a circumferential direction.

In a multiphase hydrogen permeation alloy comprising a phase in charge of hydrogen permeation and a phase in charge of hydrogen embrittlement resistance, a structure in which the phase in charge of hydrogen permeability is continuously interconnected and in which more preferably the growth direction of the aforementioned phase in charge of hydrogen permeation lies aligned in the thickness direction of the permeation membrane. As the hydrogen permeation alloy, an Nb—Ti—Co alloy is exemplified, wherein the phase in charge of hydrogen permeability is made of an (Nb, Ti) phase and the aforementioned phase in charge of hydrogen embrittlement resistance is made of a CoTi phase. By virtue of the fact that the growth direction of the phase in charge of hydrogen permeation lies aligned in the thickness direction of the permeation membrane, the hydrogen permeation pass length becomes short to give further improved hydrogen permeation property.

A (Nb, Ti) phase in an Nb—Ti—Co alloy is composed of a granular structure. The Nb—Ti—Co alloy is preferably subjected to heat treatment at 800° C. or more so that the eutectic structure in the casted state can be changed to a granular structure. The Nb—Ti—Co alloy used there is preferably NbxTi(100-x-y)Coy, (x≦70, 20≦y≦50 (mol %)). By properly predetermining the heating temperature and time, the resulting alloy exhibits improved hydrogen permeability in combination with a good hydrogen embrittlement resistance characteristic in the CoTi phase, making it possible to provide a practical hydrogen permeable membrane having an advantageously high performance.

A hydrogen permeable module includes a hydrogen permeable membrane that permeates hydrogen, an outer peripheral part of the hydrogen permeable membrane being restricted, an inside of the outer peripheral part of the hydrogen permeable membrane being not restricted. The hydrogen permeable module permeates the hydrogen by constantly keeping a pressure of a primary side to a pressure that is equal to or more than a pressure of a secondary side. The inside of the outer peripheral part of the hydrogen permeable membrane is not restricted so as to be capable of expanding to the secondary side.
