## Title
Pneumatic pressure and vacuum device

## Abstract

Disclosed is a pneumatic pressure and vacuum device that allows a user to adjust the duration of either pressure or vacuum that is applied to a pneumatic adult toy. A solenoid valve is used that is controlled by a solenoid for opening and closing ports that apply pressure and/or vacuum to a pneumatic adult toy. A timer is utilized to independently control the on and off times of the solenoid valve, so that vibrational frequency, as well as the amplitude of pressure and vacuum can be adjusted.

## Background
BACKGROUND OF THE INVENTION
Pneumatic devices are used extensively in mechanical systems. Pneumatic systems typically use air as a medium to control various actions in mechanical systems. For example, pneumatic systems can operate valves, create forces in pneumatic cylinders and various other functions. Pneumatic systems typically use air compressors that create a wide range of pressure values for various purposes. Such systems are useful, simple and easy to implement.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic block diagram of a pneumatic system 100. As illustrated in FIG. 1, the pneumatic system 100 includes a compressor/vacuum pump 102. The compressor/vacuum pump 102 has a vacuum port 104 and a pressure port 106. Vacuum line 110 is connected to the vacuum port 104 of compressor/vacuum pump 102, while pressure line 108 is connected to the pressure port 106 of compressor/vacuum pump 102. The pressure line 108 and the vacuum line 110 are connected to a solenoid valve 112. The solenoid valve 112 is operated by a solenoid 128. Solenoid valve 112 may be connected to a pressure line 108, a vacuum line 110, or both a pressure line 108 and vacuum line 110. Solenoid 128 functions to open and close one or more valves in solenoid valve 112. For example, solenoid 128, upon application of a voltage from power supply 124, may open a port in the solenoid valve 112 that is connected to the pressure line 108 and the output line 114. Upon removal of the voltage from solenoid 128, the port connecting pressure line 108 and output line 114 is closed. Alternatively, another port may be opened upon application of a voltage to solenoid 128, which connects the vacuum line 110 to the output line 114. These functions are disclosed in more detail below.
Accordingly, the embodiment of FIG. 1 allows a user to have individual control of the expansion and contraction of the pneumatic adult toy 126, including the duration periods for the application of pressure, or the non-application of pressure, as well as the duration of the application of a vacuum, or the non-application of a vacuum, to the pneumatic adult toy 126. As such, the vibrational frequency, as well as the size of the pneumatic adult toy 126, can be controlled with a high degree of precision by using adjustment knobs 118, 120, which control two individual timers. This also allows the user to control the amount of vacuum desired. For pressure toys, control over the duration of application of pressure versus the non-application of pressure, or the duration of vacuum, controls the size of the pneumatic adult toy 126, which creates a repeating vibrational cycle. With respect to vacuum adult toys, the duration of the period of removal of air from the pneumatic adult toy 126 versus non-application of vacuum, or the application of pressure, controls the amount of vacuum created in the pneumatic adult toy 126.
The timer relay 116 may comprise, in one embodiment, two timers that vary from zero to 60 seconds. For example, adjustment knob 118 may vary the duration of the application of pressure from pressure line 108 to output line 114 for an adjustable period of from zero to 60 seconds, while adjustment knob 120 may vary the duration of the non-application of pressure, or the application of vacuum to the pneumatic adult toy 126 for an adjustable period of from zero to 60 seconds.
FIG. 2 is a schematic block diagram of an embodiment of a pressurized system 200. As illustrated in FIG. 2, solenoid valve 202 has a pressure port 216 that is connected to a pressure line 210 from a compressor (not shown). Solenoid 204 is actuated by a timer 208 that controls the application of power source 212 to the solenoid 204. Solenoid 204 opens and closes a valve that connects port 214 from the pressure port 216, to the output port 218. Knob 220 adjusts the duration of the period during which the port 214 is open, which connects pressure port 216 to output port 218. Adjustable knob 222 adjusts the duration of the period during which port 214 is closed. In this manner, the duration during which the pressure line 210 is connected to the pneumatic adult toy 206 is controlled by adjustment knob 220, while the duration period during which pressure line 210 is not connected to the pneumatic adult toy 206, is controlled by adjustment knob 220.
FIG. 3 is a schematic block diagram illustrating a low pressure pneumatic system 300. As illustrated in FIG. 3, solenoid valve 302 is controlled by a solenoid 304. Solenoid 304 is, in turn, controlled by timer 310, that is connected to a power source 314. Timer 310 adjusts the time during which the power source 314 is connected to the solenoid 304. Adjustment knob 322 adjusts the amount of time that the power source 314 is connected to the solenoid 304. When the solenoid 304 is connected to the power source 314, port 316 is open, such that the output port 320 is connected to the vacuum port 318. In this manner, the vacuum line 312 is connected to the pneumatic adult toy 306 during that time period. When the power source 314 is not connected to the solenoid 304, port 316 is closed, so that there is no communication between the vacuum port 318 and the output port 320. Adjustment knobs 322, 324 therefore control the amount of time that the solenoid 304 is powered by the power source 314, which, in turn, controls the duration of time that the port 316 is open.
FIG. 4 is a schematic block diagram of another embodiment of a high and low pressure system 400. As illustrated in FIG. 4, a solenoid valve 402 includes a port 416 that connects the pressure port 420 to the output port 424. Solenoid 402 also includes a port 418 that connects the output port 424 to vacuum 422. Pressure port 420 is connected to the pressure line 410 that is connected to a compressor/vacuum pump (not shown). Vacuum port 422 is connected to a vacuum line 412, which is also connected to the pressure/vacuum pump (not shown). Solenoid 404 operates the solenoid valve 402 in response to the application of power from power source 414. Timer 408 includes adjustment knobs 424, 426. Adjustment knob 424 controls the time during which power from power source 414 is applied to solenoid 404. Adjustment knob 426 controls the amount of time that the power source 414 is disconnected from the solenoid 404. Solenoid 404 may comprise multiple solenoids that operate valves that control ports 416, 418. In accordance with one embodiment, adjustment knob 424 may control the duration of time during which port 416 is open, so that pressure from pressure line 410 is applied to the output port 424 and pneumatic adult toy 406. Similarly, adjustment knob 426 may adjust the time during which port 418 is open and allows vacuum from vacuum 412 to be communicated to the output port 424 and the pneumatic adult toy 406. Timer 408 may be constructed so that the periods generated by the adjustment knobs 424, 426 do not overlap. In this manner, pressure can be applied to the pneumatic adult toy 406 during a first period and a vacuum can be applied to the pneumatic adult toy 406 during a second period. As such, both the size of the pneumatic adult toy, as well as the vibrational frequency of the pneumatic adult toy 406, can be controlled by a user, with adjustment knobs 424, 426.
