PISTON VACUUM PUMP

In standard piston pumps, the continuous up and down movement of the piston is generated by means of a crank mechanism. This is disadvantageous, however, when trying to obtain a final pressure which is as low as possible, as the time interval in which the enclosed gas is compressed past the outlet pressure, thus enabling the opening of the outlet valve, approaches zero with the falling inlet pressure. This prevents an effective discharge of gas through the outlet valve, with the falling inlet pressure, and complicates the temporally precise control of the outlet valve in relation to the piston movement. According to the invention, a planet gear is used to guide the bearing of the connecting rod to a hypocycloid or epicycloid, such that the part of the curve which is crossed while the gas is compressed to a maximum corresponds approximately to a semicircle. As the length of the connecting rod is equal to the radius of the arc, the piston movement almost comes to a standstill during the maximum ...

EVACUATION DEVICE

The evacuation device removes air from a container via a one-way valve and includes a motor with a rotating shaft that extends along an axis line. The shaft is operably interconnected to a reciprocating element reciprocally movable within a chamber along a direction parallel to the axis. Reciprocal motion of the reciprocal element draws/exhausts air into/from the chamber. To facilitate the operable interconnection, the evacuation device includes a cam having a cylindrical sidewall mounted to the rotating shaft. Disposed circumferentially into the cylindrical sidewall is a channel. The evacuation device further includes a yoke connected to the reciprocal element and having a follower element received in the channel. Cam rotation causes the follower element to move with respect to the channel, converting rotational motion to linear translation. The evacuation device may include pressure adjustment. In one embodiment, the pressure adjustment includes a rotating ring with a series of holes.

The disclosure is generally directed to a wheel-mounted, centrifugally activated, air compressor that will automatically inflate an inflatable vehicle tire back to the proper pressure level when small under-inflation situations occur (e.g., the occurrence of small-to-medium air leaks in a tire). Moreover, the device can be easily attach or fitted into the design of a steel or aluminum wheel, or fitted into a hubcap without modifying the standard design of the wheel-hub assembly. The wheel-mounted device includes a mounting base, cylinder assemblies, and spring-biased centrifugal arms, and is designed to convert changes in the centrifugal force felt by the centrifugal arms as wheel rotation accelerates or decelerates/stops into varying force exerted on positive-displacement pistons. This in turn actuates positive-displacement pumping action at the cylinder assemblies, each of which can provide a short burst of pressurized air into the charging line connected into the associated tire with ...

An air compressor , comprising:a base frame defining a first mounting hole, which allows a pinion driven by a motor to pass, and a second mounting hole for receiving therein a bearing which includes an outer ring, an inner ring defining a central hole, and a plurality of rolling balls disposed therebetween;a cylinder fixed to or formed integrally with the base frame;an air storage container provided with one or more outlet tubes, and connected and communicated with the cylinder;a gear in mesh with the pinion; anda crank mechanism including a counterweight provided on the gear, a crankpin connected with a piston, and a shaft element having a first end, which defines a central cylindrical recess, and a second end, wherein the second end has a diameter greater than the first end, thus forming an annular step therebetween, the second end of the shaft element being fixed to a center of the gear, the first end of the shaft element being inserted through the central hole of the inner ring of the bearing and being hitted by a striking tool to form an outwardly extending rim on the first end of the shaft element, so that the bearing is firmly fixed between the outwardly extending rim and the annular step of the shaft element.2. The air compressor of claim 1 , wherein a cutout ...
