摘要： Known all wheel steer arrangements use standard spool-type valves which are inherently subject to leakage that results in the front and rear wheels getting out of synchronization due to the leakage. In the subject invention, a hydraulic system has front and rear pairs of steerable wheels respectively interconnected by front and rear fluid actuated mechanisms. A steering valve delivers pressurized fluid to the front fluid actuated mechanism for steering of only the front pair of wheels and to both the front and rear fluid actuated mechanisms to steer the front and rear pairs of wheels simultaneously but in opposite directions. Furthermore, a rear steer valve mechanism is provided to independently direct pressurized fluid to the rear fluid actuated mechanism to steer the rear pair of wheels independent of the front pair of wheels. A normally open pilot operated poppet valve and a pair of normally closed pilot operated poppet valves are utilized to provide control for the various modes of operation and to provide separation of the fluid between the front and rear fluid actuated mechanisms when they are being operated independently. By utilizing pilot operated poppet valves, the leakage thereacross is substantially reduced and the synchronization between the front and rear pair of wheels is generally maintained.
摘要翻译：众所周知的所有的轮子转向装置都使用标准的阀芯阀门，这些阀门本身就会发生泄漏，导致前轮和后轮由于泄漏而失去同步。在本发明中，液压系统具有分别由前后流体致动机构互连的前后对的可转向轮。转向阀将加压流体输送到前流体致动机构，用于仅转向前一对车轮以及前和后流体致动机构，以同时但相反的方向转向前后对的车轮。此外，后转向阀机构设置成独立地将加压流体引导到后流体致动机构，以独立于前一对车轮转向后一对车轮。常开的先导式提升阀和一对常闭先导操作的提升阀用于为各种操作模式提供控制，并且当它们独立地操作时，在前和后流体致动机构之间提供流体分离。通过利用先导式提升阀，其中的泄漏量大大减小，并且通常保持前后一对车轮之间的同步。

摘要： A boring tool assembly is provided and has a cutting tool mounted on one end thereof and permits the boring of a straight hole through a member. The boring tool assembly includes a boring bar having integral guide members disposed thereon that follows behind the cutting tool and maintains contact with the machined surface just cut in order to keep the cutting tool in proper alignment. To permit the continued use of the boring bar after the outer diameter of the cutting tool has been reduced due to wear, each of the integral guide members are resiliently mounted on the boring bar. This permits the guide members to collapses inwardly to maintain a perfect fit with the pilot pore while maintaining bearing contact of the guide members with the pilot bore. The positive bearing contact helps to provide a dampening feature for the boring bar and a spring type force for the hardened guide members. A resilient member is mechanically secured in respective slots to provide the resilient mounting of the hardened guide members to the boring bar.
摘要翻译：提供了一种钻孔工具组件，并且具有安装在其一端上的切削工具，并且允许通过构件钻出直孔。钻孔工具组件包括镗杆，其具有设置在其上的整体引导构件，其在切割工具后面保持与刚切割的加工表面的接触，以保持切割工具正确对准。为了允许在切削工具的外径因磨损而减小后继续使用镗杆，每个整体引导构件弹性地安装在镗杆上。这允许引导构件向内折叠以保持与导向孔的完美配合，同时保持引导构件与引导孔的轴承接触。正向轴承接触有助于为镗杆提供阻尼特征和用于硬化的导向构件的弹簧型力。将弹性构件机械地固定在相应的槽中，以将硬化的导向构件弹性安装到镗杆上。

摘要： A hydraulic pressure transformer for the conversion of an input hydraulic power to an output hydraulic power includes a housing with a generally planar face surface and a plurality of ports opening at the face surface. A barrel which is rotatable about an axis includes a generally spherical end face and a plurality of cylinders opening at the end face. A port block interposed between the barrel and the housing is rotatable about the axis. The port block has a first face surface, a second face surface and a plurality of ports extending between the first face surface and the second face surface. The ports selectively fluidly interconnect the plurality of cylinders in the barrel with the plurality of ports in the housing. The first face surface is generally spherical and abuts the end face of the barrel. The second face surface is generally planar and abuts the face surface of the housing.

摘要： A boring tool assembly is provided and has a cutting tool mounted on one end thereof and permits the boring of a straight hole through a member. The boring tool assembly includes a boring bar having integral guide members disposed thereon that follows behind the cutting tool and maintains contact with the machined surface just cut in order to keep the cutting tool in proper alignment. To permit the continued use of the boring bar after the outer diameter of the cutting tool has been reduced due to wear, each of the integral guide members are resiliently mounted on the boring bar. This permits the guide members to collapses inwardly to maintain a perfect fit with the pilot pore. This collapse inwardly of the guide members is important to maintain bearing contact of the guide members with the pilot bore if the hole being cut by the cutting tool reduces in size due to wear or if the cutting tool has been re-sharpened or replaced with a different cutting tool. A resilient member is bonded in respective slots between the bottom of the associated slot and the guide member to provide the resilient mounting of the hardened guide members to the boring bar.
