The actuation linkage assembly is configured with high mechanical advantage. The actuation linkage assembly can be part of a movable inter-stage vane guide assembly in a compressor such as for example a centrifugal compressor, which may be part of a chiller such as in a HVAC system.

A reclining device includes: a first member; a pawl having external teeth; a second member; a cam; and a spring, which biases the cam to move the pawl in the direction where the external teeth engage with the internal teeth, the pawl guide includes a first pawl guide and a second pawl guide, a wedge-shaped space is formed between the pawl and the first pawl guide, and a width of the wedge-shaped space is gradually reduced in a direction where the pawl is guided, an end of the spring is inserted into the wedge-shaped space, and the end of the spring is directly wedged into the wedge-shaped space, thereby pressing the pawl against the second pawl guide.

A spring component for a ratcheting mechanism, such as a ratchet wrench. The spring component is shaped to be retained in a recess without any special machining. For example, the spring component can be retained at three abutment points. A leaf of the spring component can abut a pawl, and a base portion opposite the leaf can abut the drive gear. Support arms can abut the sidewall of the recess to retain the spring component within the recess without the need for special machining or tooling.

A wave-wind mutually supplementing power supply system for continuous power generation is disclosed. The system of the present invention has a wave kinetic energy module (10), which comprises a wave energy harnessing unit (100), a transmission shaft (110), a generator unit (120), a torque adjusting unit (130) and an automatic control unit (140). The wave kinetic energy module (10) is disposed on/in a sea and may generate electricity through the motion of sea water. The electricity so generated is combined with a wind power generation device to provide continuous power generation. The automatic control unit (140) has a microprocessor (141) and a sea water motion sensor unit (142) so as to adjust the torque of the transmission shaft and control the activation of the generator unit according to the motion of the sea water.

In the coupling of bi-directional, non-freewheeling-type DC motors (24,25) to the pulling spool (23) of a canopy (11) deployment strap (21,22) and to a take-up roller (15), ratchet gears (26,27) assure automatic alignment and synchronization of the deployment and retraction mechanisms. The reverse direction rotation of the unwinding motor can be uninhibited through the slipping of its ratchet gear when the winding motor is slow to take up the pulling strap or the tarp (11) being wound thereon. The slipping provides sufficient slack to accommodate changes of spool and roller diameters as more material is successively wound thereon. A friction brake acting against a flange of die spool keeps it from spinning freely when not engaged by the motor. Winding motors can be protected against excessive power use by measuring the level of drawn current with a digital ammeter. If the current exceeds a threshold level of operation, a timer is started. As soon as a given absolute safe period of operation is surpassed, a breaker switch is tripped interrupting the motor power supply. A plural number of trip points can be programmed into the device.

The invention relates to a device including: a movable element (1) comprising teeth (11; 11.sub.i, i, 11.sub.i+1, 11.sub.i+2, 11.sub.i+3, 11.sub.i+4); a driving element (2) for engaging with the teeth (11; 11.sub.i, 11.sub.i+1, 11.sub.i+2, 11.sub.i+3, 11.sub.i+4) of the movable element (1) so as to set the movable element (1) in motion in a direction of movement; an actuator element (3) capable of generating an alternating movement so as to move the driving element (2) according to at least two phases, i.e. a driving phase, during which the driving element (2) is engaged with a tooth (11; 11.sub.i, 11.sub.i+1, 11.sub.i+2, 11.sub.i+3, 11.sub.i+4) of the movable element (1), and a return phase without driving, during which the driving element (2) is shifted with respect to the movable element (1); and a first indexing element (4), which includes a first indexing finger (41) to be positioned between two teeth (11; 11.sub.i, 11.sub.i+1, 11.sub.i+2, 11.sub.i+3, 11.sub.i+4) of the movable element (1), and which is connected to the actuator element (3) in order to move the driving element (2) and the first indexing finger (41) simultaneously.

The first ratchet mechanism includes a first drive input gear, a first drive output gear, and a first coupling member. The second ratchet mechanism includes a second drive input gear, a second drive output gear, and a second coupling member. The link member, due to a thrust movement of the first coupling member in a direction separating from the first drive output gear, causes the second coupling member to move in a direction approaching the second drive output gear, and the link member, due to a thrust movement of the second coupling member in a direction separating from the second drive output gear, causes the first coupling member to move in a direction approaching the first drive output gear.

The second rotary transmission device comprises a second connecting and disconnecting device, and the second rotary transmission device has a second output shaft. When the gear rotates in a first rotation direction or a second rotation direction, one of the first rotary transmission device and the second rotary transmission device is driven, so that one of the connecting and disconnecting devices is driven into an engaged state, wherein one of the output shafts rotates while the other output shaft does not rotate. The actuator device according to the present disclosure has a stable connecting and disconnecting process and a stable output, and can implement double outputs by means of a single actuator. The two output shafts are symmetrically arranged with respect to a rotating shaft of the driving gear and are spaced apart by a certain distance, so that outputs of the output shafts are relatively balanced and do not interfere with each other.
