摘要： Fluid handling couplings can be made to connect and disconnect other members of a fluid handling system. For example, this document describes fluid couplings that are convenient to couple/decouple and that provide strong resistance to inadvertent disconnection when subjected to rotation while pressurized. In some embodiments, the resistance to inadvertent disconnection is facilitated by a latch mechanism of the female coupling that includes a protrusion that becomes seated in a groove of a mated male coupling.

摘要： A zero turn mower vehicle 10 includes left and right hydrostatic transmissions 11a, 11b driving wheels 15a, 15b. The transmissions 11a, 11b each include a swashplate type axial piston hydraulic pump 17 having a swashplate 22. A system 12 and method controls each pump 17. A controller 31 receives input signals and provides output signals to electric motors 33a, 33b to control each swashplate 22. Operator interface input devices 30a, 30b provide inputs to controller 31. Angle sensors 35a, 35b provide additional inputs to controller 31. Displacement amplifiers 36a, 36b amplify displacement of each swashplate 22, and torque amplifiers 34a, 34b amplify torque of electric motors 33a, 33b.

摘要： According to one aspect, a clutch mechanism includes a control member. The control member is adapted to receive motive power and includes a first dry clutch member and a first viscous clutch member. The clutch mechanism further includes an output member that includes a second dry clutch member and a second viscous clutch member. The first and second dry clutch members form a dry clutch and the first and second viscous clutch members form a viscous clutch. The clutch mechanism further includes an actuation arm coupled to at least one of the control and output members. The actuation arm is selectively controllable to effect relative movement of the control and output members such that one of the dry and viscous clutches is selectively engaged.

摘要： A hydrostatic transaxle with a bypass mechanism is disclosed, the transaxle having a center section engaged to a housing, an axial piston pump disposed on the center section and driven by an input shaft, and an axial piston motor disposed on the center section having a cylinder block engaged to a motor output shaft. The pump is controlled by a swash plate having a pair of openings through which the input shaft and a bypass actuation rod pass. The bypass actuation rod has a cam formed on a first end that engages a block lift member. When the bypass actuation rod is rotated, the cam causes the block lift member to engage and lift the cylinder block of the axial piston motor off of the center section. A brake mechanism using brake puck disposed in a pocket formed in the center section is also disclosed.

摘要： A work vehicle obtains determination information from information upon detecting inverting operation, the information upon detecting inverting operation indicating a traveling state of the work vehicle when an advancing direction detection device detects an inverting operation of an advancing direction switching device for inverting an advancing direction of the work vehicle while the work vehicle travels; decreases a first traveling instruction for allowing the work vehicle to travel in the advancing direction of the work vehicle upon the detection of the inverting operation, and increases a second traveling instruction for allowing the work vehicle to travel in the direction opposite to the advancing direction of the work vehicle upon the detection of the inverting operation, after detecting the inverting operation; and sets the first traveling instruction to 0 when speed information indicating a traveling state of the work vehicle becomes the determination information.

摘要： A launch device for a vehicle transmission includes a housing, an impeller, a turbine; and first and second clutches. The first and second clutches include first and second pistons, respectively. The first and second pistons are sealingly engaged with one another. The first clutch releaseably engages the impeller with the housing and the second clutch releaseably engages the turbine with the first piston. In an example embodiment, the first clutch is disposed radially outside of the second clutch and at least a portion of the first piston is disposed axially between the housing and the second piston. In an example embodiment, the first clutch is engaged by a first pressure, and the second clutch is engaged by a second pressure greater than the first pressure.

摘要： A novel and useful method and apparatus for generating power from pressure changes over time within a fluid. The apparatus comprises a housing (10), and a double-sided piston (12) subject to the forces brought about by the variations in pressure of the surrounding fluid and by a restoring force such as a spring (20) or other mechanism. The resulting motion of the piston is transferred to power a generator, or is used to directly perform work. The apparatus is particularly applicable to placement in the ocean or sea where the rise and fall of the tides create the variations of pressure that drive the piston within the housing. A rising tide presents a higher pressure against the face of the piston pushing it towards the back of the housing and opposing the restoring force mechanism. A falling tide presents a lower pressure against the face of the piston allowing the restoring force to move it towards the front of the housing. Energy is harvested from the movement of the piston in one or both directions either by connection to a turbine coupled to a generator or by a linkage attached to the piston that is connected to a mechanical load such as a generator, pump, etc.
摘要翻译： 一种新颖有用的方法和装置，用于在流体内随着时间内的压力变化产生功率。 该装置包括壳体（10）和受到由周围流体的压力变化引起的力和通过诸如弹簧（20）或其他机构的恢复力而产生的力的双面活塞（12）。 所产生的活塞运动被传递给发电机供电，或用于直接执行工作。 该装置特别适用于在海洋或海洋中的放置，其中潮汐的上升和下降产生驱动活塞在壳体内的压力变化。 升起的潮汐对活塞的表面施加较高的压力，将其推向壳体的后部并且与恢复力机构相对。 降落潮流对活塞的表面施加较低的压力，使得恢复力将其朝向壳体的前部移动。 通过连接到联接到发电机的涡轮或通过连接到连接到机械负载（例如发电机，泵等）的活塞的连杆，在一个或两个方向上从活塞的运动中收获能量。

摘要： A portable, rotary vane vacuum pump with an automatic vacuum breaking arrangement that vents the pump to atmosphere whenever the drive motor ceases to rotate the pump. The arrangement prevents lubricating oil in any substantial amount from being undesirably drawn into the evacuated pump when the drive motor is shut off either intentionally or unintentionally. If the system being evacuated is also still connected to the pump, the arrangement will additionally vent it and greatly limit any amount of oil that may be undesirably sucked back into it. The pump further has a primary oil container that essentially holds all of the oil for the system. The primary container is preferably made of clear, rigid plastic and is also removable from the main body of the pump so it can be quickly and easily replaced with another container of fresh oil even while the pump is still operating.
摘要翻译： 一种便携式旋片式真空泵，具有自动真空断开装置，每当驱动电机停止旋转泵时，将泵排入大气。 当驱动马达有意地或无意地被切断时，该布置防止任何实际量的润滑油不期望地被吸入抽真空泵。 如果抽真空的系统仍然连接到泵，则该装置还将排放它并且极大地限制可能不期望地被吸回到其中的任何量的油。 泵还具有基本上保持系统的所有油的主油容器。 主容器优选地由透明的刚性塑料制成，并且也可以从泵的主体移除，因此即使在泵仍在运行时也可以快速而容易地用另一容器替换新鲜的油。
