According to one aspect, a fluid control system is provided comprising a servicing tool set and at least one valve assembly comprising an actuator and a valve operationally engageable therewith; each valve comprising a valve body; each actuator comprising an actuator body having an upper base and side walls; wherein each actuator body is engageable with a valve body, and wherein the system is configured to allow: engaging the servicing tool set with an actuator and subsequently applying torque to an actuator body engaged with a valve body and thereby disengaging the actuator body from the valve body; the at least one valve assembly comprising at least one Normally Closed (NC) valve; wherein the NC valve is configured to allow activating an actuator engaged therewith with pressurized fluid and thereby opening the NC valve, wherein the actuator comprises a nipple and the servicing tool set comprises a ratchet and at least one socket engageable with the actuator body, and wherein the at least one socket is sized and shaped to accommodate the nipple, and wherein the servicing tool set is further configured to allow operationally coupling the pressurized fluid to the actuator.

A ratchet tool comprises a base, a ratchet body, a switching member and a pawl member. The base has a rail and is movable with linear motion along the rail between a first position and a second position, the ratchet body has plural teeth, and the pawl member is engaged with the switching member and comprises plural ratchet teeth, a first abutting portion and a second abutting portion. When the switching member is movable to the first position, the pawl member is pivotally rotated to a third position to make the ratchet teeth mesh with the teeth and the first abutting portion abut against the base, therefore the ratchet body enables to rotate along a first rotation direction. When the switching member is movable to the second position, the pawl member is pivotally rotated to a fourth position to make the ratchet teeth mesh with the teeth and the second abutting portion abut against the base, therefore the ratchet body enables to rotate along a second rotation direction.

An air ratchet wrench has a body, a tool, and a restrictor. The body has two panels disposed at a spaced interval. Each panel has a through hole coaxially aligned with the through hole of the other panel. A first surface is located on a backside of one of the two panels away from the other panel, and a second surface is located on a backside of the other panel. The tool is assembled from the first surface, having a first end and a second end. The first end has an outer diameter larger than an inner diameter of the through hole of the panel that has the first surface. The second end passes through the two through holes, and protrudes on the second surface. The restrictor is sheathed on the tool and constrains the two panels from parting with the first end.

A ratchet wrench having multiple driving modes with torque sensing function includes an annular head, a driving unit, a control unit, a rotary member, a forcing unit and at least one torque sensor. The annular head receives the driving unit therein and a shaft extends from the annular head. The driving unit has a first toothed ring engaged with a first pawl, and a second pawl engaged with inner teeth of the annular head. The rotary member is rotatably inserted in the shaft, and has two ends to the driving unit and the forcing unit respectively. The forcing unit includes a tubular handle and a display unit. The torque sensor is mounted on the shaft. The shaft inserts into an axial chamber of the handle. The torque sensor is positioned between the axial chamber and the shaft. When the shaft is bended by the handle to produce a deformation. The torque sensor senses the deformation of the shaft to generate a torque sensing signal, so that the display unit converts the torque sensing signal to a torque value and displays the torque value.

The invention provides, in another aspect, an impact tool comprising a housing, a motor having an output shaft defining a first axis, a drive shaft rotatably supported by the housing about a second axis oriented substantially normal to the first axis, a gear coupled for co-rotation with the drive shaft, an impact mechanism coupled between the motor and the drive shaft and operable to impart a striking rotational force to the drive shaft, the impact mechanism including, an anvil rotatably supported by the housing and coupled to the drive shaft, the anvil including a pinion engaged with the drive shaft gear, a hammer coupled to the motor to receive torque from the motor and impart the striking rotational force to the anvil, and a spring washer exerting a preload force on the pinion to maintain the pinion meshed with the drive shaft gear.

A ratchet tool including a handle housing including a grip, the handle housing defining a longitudinal axis. The ratchet tool also includes a ratchet assembly including a pawl and an output shaft. The pawl is moveable between a first position in which the pawl is operatively coupled to drive the output shaft in a first direction and a second position in which the pawl is operatively coupled to drive the output shaft in a second direction opposite the first direction. A switch is disposed in an aperture in the generally tubular surface of the handle housing, the switch having an external actuation surface for engagement with an operator's hand. The switch is slideable with respect to the handle housing in a direction generally parallel to the longitudinal axis. A linkage is disposed between the switch and the ratchet assembly configured to move the pawl between the first and second positions.

A ratchet mechanism includes: a first member having an annular surface provided with a plurality of teeth arranged parallel to its axial direction; a second member configured to be rotatable relative to a circumferential direction of the annular surface; at least two first drive transmission members arranged on the second member, each including at least one ratchet tooth, the first drive transmission members being configured to be engaged with the teeth to transmit motion between the first member and the second member, where the ratchet tooth of each of the first drive transmission members is in different engaged states with the teeth.

The present invention surrounds to a ratchet apparatus, system and use thereof. The invention is presented to provide additional mechanical advantage and added angular engagement of a ratcheting wrench. In particular the present invention provides increased torque and angular engagement within a compact space without requiring an extended handle, wherein an extended handle reduces portability and further restricts access and movement within confined spaces.

A driving tool is provided, including a grip body, a main body, a driving assembly, a press handle, a driven member and a toothed bar. The main body is rotatably disposed on the grip body. The driving assembly is arranged on the main body. The press handle is disposed on the grip body to drive the driven assembly. The driven assembly is disposed on the main body. The toothed bar is connected to the driven assembly and the driving assembly.
